The sun is vertically overhead at the tropic of Caprison in

Answer Details

The sun is vertically overhead at the tropic of Capricorn on December 22nd. To understand why, we need to know a few things about the Earth's tilt and its movement around the sun. The Earth is tilted on its axis at an angle of about 23.5 degrees. This tilt is what gives us our seasons. During the year, the Earth moves around the sun in an elliptical path. On two specific days, called the solstices, the sun reaches its highest or lowest point in the sky. These are the days when the tilt of the Earth is most noticeable. On December 22nd, the Northern Hemisphere is tilted away from the sun. This means that the sun appears lower in the sky and its rays are more spread out. Meanwhile, the Southern Hemisphere is tilted towards the sun. This tilt causes the sun to appear higher in the sky and its rays to be more concentrated. The tropic of Capricorn is located at about 23.5 degrees south of the equator. On December 22nd, the sun is directly overhead at this latitude because the tilt of the Earth causes the sun's rays to be focused at that point. In summary, on December 22nd, the sun is directly overhead at the tropic of Capricorn because of the Earth's tilt and its position in its orbit around the sun.

Which of the following is a feature of heavy industries?

Answer Details

A feature of heavy industries is that they are capital-intensive. This means that they require a significant amount of investment in machinery, equipment, and infrastructure to operate efficiently. Unlike light industries, which typically involve smaller-scale operations, heavy industries involve large factories or plants that are designed to produce goods on a larger scale. The term "heavy" in heavy industries refers to the nature of the products being manufactured, such as machinery, steel, chemicals, and automobiles. These products often require heavy machinery and specialized equipment to produce. Due to their large-scale operations and the need for substantial capital investment, heavy industries usually have a longer payback period for their investments. Some examples of heavy industries include manufacturing plants for automobiles, oil refineries, steel mills, and chemical production facilities. These industries usually have a higher production capacity and require a significant amount of resources and manpower to operate. In summary, heavy industries are characterized by their capital-intensive nature, large-scale operations, and production of goods that require heavy machinery. These industries play a crucial role in the economy by producing essential products and contributing to employment opportunities.

A line joining all points of equal salinity is an

Answer Details

A line joining all points of equal salinity is called an isohaline. In simpler terms, an isohaline is a line that connects points in a body of water that have the same level of salinity or saltiness. It is similar to a contour line you might see on a map that connects points of equal elevation. Salinity refers to the amount of salt dissolved in water. Different areas of the ocean, sea, or even a lake can have varying levels of salinity. An isohaline helps us visualize these varying levels by connecting the points with the same salinity. By studying and mapping isohalines, scientists can gain valuable insights into the distribution and movement of saltwater in different bodies of water. This information is important for understanding ocean currents, marine life habitats, and even for managing freshwater resources. To summarize, an isohaline is a line that connects points with the same salinity in a body of water. It helps us understand the distribution and movement of saltwater and is valuable in various scientific studies and resource management.

The part of the earth crust covered by water bodies is known as the

Answer Details

The part of the earth's crust covered by water bodies is known as the hydrosphere. The hydrosphere includes all the water on Earth, including oceans, seas, lakes, rivers, and even groundwater and atmospheric water vapor.
The hydrosphere plays a crucial role in supporting life on Earth. It provides habitats for a wide range of organisms and helps regulate the planet's climate. The hydrosphere is also a vital source of freshwater, which is essential for drinking, agriculture, and various other human activities.
The term "sial" refers to the upper part of the earth's crust, which is made up of lighter rocks like granite and makes up the continents. Therefore, it is not the correct answer for this question.
The stratosphere, on the other hand, is a layer of the Earth's atmosphere located above the troposphere. It extends from about 10 kilometers (6.2 miles) to 50 kilometers (31 miles) above the Earth's surface. The stratosphere contains the ozone layer, which helps protect the Earth from harmful ultraviolet radiation. However, it is not related to the crust or water bodies, so it is not the correct answer either.
In summary, the correct answer is the hydrosphere, which refers to the part of the Earth's crust covered by water bodies.

Which of the following represents the correct sequence in which denudation occurs?

Answer Details

Denudation is the process of wearing away the Earth's surface by various agents such as water, wind, and ice. It involves the removal and transportation of rocks, sediments, and soil. The correct sequence in which denudation occurs is:
Weathering → Erosion → Deposition
1. Weathering: This is the first step in denudation. Weathering refers to the breakdown and decomposition of rocks and minerals at or near the Earth's surface. It can occur through physical, chemical, or biological processes. Physical weathering involves the mechanical breakdown of rocks into smaller fragments due to factors like temperature changes, frost action, or plant roots. Chemical weathering involves the alteration of rock composition through processes like dissolution, oxidation, or hydrolysis. Biological weathering refers to the breakdown of rocks by living organisms such as plants and animals.
2. Erosion: Once weathering has broken down the rocks, erosion takes place. Erosion is the process of removing and transporting the weathered materials from their original location to a new location. This is often done by agents such as water, wind, glaciers, or gravity. For example, water erosion occurs when rainfall or flowing water carries away sediments, creating channels, gullies, and valleys. Wind erosion happens when strong winds pick up and transport loose particles, leading to the formation of sand dunes and desert landscapes.
3. Deposition: After weathered materials have been eroded and transported, they are eventually deposited. Deposition occurs when the eroded particles and sediments settle down and come to rest in a new location. This can happen when the transporting agent loses energy, such as when a river slows down or when wind speed decreases. Deposited materials can form various landforms such as deltas, alluvial plains, or beaches.
In summary, denudation starts with weathering, where rocks are broken down. Then erosion takes place, transporting the weathered materials. Finally, the eroded materials are deposited in a new location.

Buying and selling of goods and services within a country is termed as

Answer Details

The buying and selling of goods and services within a country is known as internal trade.

Internal trade refers to the exchange of goods and services between individuals, businesses, and organizations within the borders of a country. It involves the transfer of goods and services from producers to consumers or from one business to another within the same country.

For example, when you go to a local store to buy groceries or when a company sells its products to customers within the country, it is considered internal trade.

Internal trade is an essential part of a country's economy as it enables the circulation of goods and services within the country, stimulates economic growth, creates job opportunities, and fulfills the needs and wants of the people.

International trade, on the other hand, refers to the exchange of goods and services between different countries. Barter is a system of trade where goods or services are exchanged directly without the use of money. Foreign trade specifically refers to the trade between different countries or the import and export activities of a country.

Therefore, in this context, the correct term for the buying and selling of goods and services within a country is internal trade.

Which of the following is not a plantation crop?

Answer Details

Rye is not a plantation crop. Plantation crops are large-scale crops that are grown specifically for commercial purposes, often on plantations or large farms. These crops are usually labor-intensive and require specialized farming techniques. Cocoa, oil palm, and rubber are all examples of plantation crops. Cocoa is the main ingredient in chocolate, oil palm produces palm oil used in various products, and rubber is used to make tires and other rubber products. On the other hand, rye is a grain crop that is typically grown in small to medium-sized farms. It is used primarily for making bread, whiskey, and animal feed. Unlike plantation crops, rye does not require extensive labor or specialized farming techniques. In summary, rye is not a plantation crop because it is grown on smaller farms and does not have the same commercial scale as crops like cocoa, oil palm, and rubber. These plantation crops have large-scale production and are used in various industries.

Which of the following stations is situated in a region of tropical monsoon climate?

Answer Details

**Bombay (Mumbai)** is situated in a region of tropical monsoon climate. Tropical monsoon climate is characterized by high temperatures and heavy rainfall throughout the year, with distinctive wet and dry seasons. In this climate, the wet season is associated with the monsoon winds, which bring abundant rainfall. The dry season, on the other hand, is characterized by little to no rainfall. Mumbai experiences this type of climate due to its location on the western coast of India. The Arabian Sea to the west and the Western Ghats mountain range to the east influence the city's climate. The monsoon winds blow from the southwest during the wet season (June to September), bringing intense rainfall to the region. Mumbai receives a significant amount of rainfall during this period, accounting for a large portion of its annual precipitation. During the dry season (October to May), Mumbai experiences less rainfall, but the temperatures remain relatively high. The average temperature ranges from 25 to 35 degrees Celsius (77 to 95 degrees Fahrenheit) throughout the year. In summary, Mumbai (Bombay) is situated in a region of tropical monsoon climate due to its location on the western coast of India, which experiences high temperatures and heavy rainfall during the wet season, and relatively lower rainfall during the dry season.

A settlement where two rivers meet is called a

Answer Details

A settlement where two rivers meet is called a confluence town. This term is used to describe a place where two rivers merge or come together. It is also known as a river confluence or simply a confluence. In a confluence town, the two rivers join and flow as one. This merging of rivers creates a unique geographical feature and often leads to the formation of a settlement. The rivers may flow side by side before merging, or one river may flow into the other. The confluence point can be visible as a distinct meeting point or an area where the waters mix. Confluence towns have been historically significant because they often provided essential resources and transportation routes. The availability of water from two rivers made these settlements ideal for various activities such as fishing, trade, and agriculture. The confluence also facilitated transportation and trade routes as it served as a natural meeting point for people traveling along the rivers. These settlements tend to develop into vibrant communities, attracting people for their economic advantages and accessibility. Over time, confluence towns may grow and expand, becoming important centers of commerce, culture, and administration. In summary, a settlement where two rivers meet is called a confluence town. It is a place where two rivers merge or come together, offering valuable resources and opportunities for economic and social development.

Exports from Mali are most likely to pass through the sea port at

Answer Details

Exports from Mali are most likely to pass through the sea port at Abidjan. Abidjan is the **largest port in West Africa** and is strategically located on the Gulf of Guinea. It has extensive infrastructure, including deep-water berths and modern cargo handling equipment, making it capable of handling large volumes of goods. Mali is a landlocked country, meaning it does not have direct access to the sea. Therefore, to export its goods, Mali needs to rely on neighboring countries with access to the sea. Abidjan, located in Ivory Coast, is the **most convenient sea port for Mali**. It is relatively close in proximity to Mali and has well-developed road and rail connections, making it an ideal choice for transporting goods from Mali to the port. Furthermore, Abidjan offers a wide range of services to facilitate trade, including customs clearance, storage facilities, and efficient cargo handling. It is also a hub for international shipping, with connections to various ports worldwide, enabling Mali to access global markets for its exports. In summary, due to its geographical proximity, well-developed infrastructure, and convenient transportation links, exports from Mali are most likely to pass through the sea port at Abidjan.

Plateaux formed together with fold mountains are best described as

Answer Details

Plateaux formed together with fold mountains are best described as "intermountain plateaus." Intermountain plateaus are large, elevated flat lands that are found between different mountain ranges. These plateaus are typically formed when tectonic forces cause the Earth's crust to buckle and fold, creating fold mountains. As these mountains rise, the surrounding areas are also uplifted, resulting in the formation of plateaus. Unlike regular plateaus, intermountain plateaus are not as deeply dissected by erosion. This means that they generally have a more even and flat topography compared to other types of plateaus. However, they still exhibit some degree of ruggedness due to the uplift and folding processes that occurred during their formation. Overall, intermountain plateaus are important features of the Earth's landscape. They provide a transitional zone between mountainous regions and the lower-lying areas beyond, and they often serve as essential water catchment areas, playing a crucial role in supplying water to rivers and streams. Their relatively flat terrain also makes them suitable for human activities such as agriculture and transportation.

A block mountain is formed as a result of

Answer Details

A block mountain is formed as a result of faulting, specifically a type of fault called a normal fault.
When the Earth's crust experiences stress, it can cause rocks to break along fault lines. In the case of a normal fault, the rocks on one side of the fault move downward relative to the rocks on the other side. This downward movement creates a step-like feature on the Earth's surface, with one side lower than the other. This step-like feature is what we call a block mountain.
As time goes on, the forces of erosion, such as wind, water, and glaciers, start to wear away at the block mountain. However, the harder and more resistant rocks that make up the mountain are less easily eroded compared to the softer surrounding rocks. This causes the block mountain to stand out even more as a prominent and elevated feature in the landscape.
So, to summarize, a block mountain is formed when the Earth's crust experiences faulting, specifically a normal fault. The downward movement of rocks on one side of the fault creates a step-like feature on the Earth's surface, which we call a block mountain. Erosion then works to shape and define the mountain's features over time.

The most common form of migration experienced in countries of Tropical Africa is

Answer Details

The most common form of migration experienced in countries of Tropical Africa is **rural-urban migration**. This refers to the movement of people from rural areas, such as villages and small towns, to urban areas, such as cities and towns. There are various reasons why rural-urban migration is prevalent in Tropical Africa. One of the main factors is the search for better economic opportunities. Urban areas tend to offer more job opportunities, higher wages, and better living conditions compared to rural areas. Many people from rural communities migrate to cities in hopes of finding better employment and improving their standard of living. Another important factor contributing to rural-urban migration is the availability of social amenities and services in urban areas. Cities often have better access to education, healthcare, infrastructure, and recreational facilities. People may migrate to urban centers to access these services and provide better opportunities for their families. Moreover, urban areas serve as economic and cultural hubs, attracting people from rural areas seeking to benefit from the diversity and dynamism of city life. Cities offer a wide range of social and cultural activities, entertainment options, and opportunities for networking and socializing. However, it is important to note that rural-urban migration also presents some challenges. The rapid influx of people into cities can lead to overcrowding, strain on infrastructure, and increased competition for resources and jobs. Additionally, migration can have an impact on rural communities as they may experience a loss of human capital and skills. In summary, rural-urban migration is the most common form of migration in countries of Tropical Africa due to the search for better economic opportunities, access to social amenities, and the attraction of urban culture and lifestyle. While it brings benefits to individuals and urban areas, it also poses challenges that need to be addressed for sustainable development.

Answer Details

The annual range of temperature is calculated by subtracting the lowest temperature of the year from the highest temperature of the year. From the table, the highest temperature is 32oC (in April) and the lowest is 22oC (in January). Therefore, the annual range of temperature is 32 - 22 = 10oC.

Soil erosion by action of rain can be caused by all of the following except

Answer Details

Soil erosion by rain can occur when the force of raindrops and the resulting surface runoff remove the top layer of soil. This process can be harmful and lead to the loss of fertile soil needed for growing crops and plant growth. There are several factors that can contribute to soil erosion by rain, but one of the options mentioned does not cause it. Let's analyze each option:

Tropical rainstorms: Tropical rainstorms are often associated with heavy rainfall and intense precipitation. The large amount of rainwater can create powerful runoff that can wash away soil particles and contribute to erosion. Therefore, tropical rainstorms can indeed cause soil erosion by rain.

Scanty vegetation: Vegetation, such as plants and trees, plays a crucial role in preventing soil erosion. The roots of plants help hold the soil together, reducing the impact of raindrops and preventing excessive runoff. When vegetation is sparse or absent, there are no roots to anchor the soil, making it more vulnerable to erosion. So, scanty vegetation can contribute to soil erosion by rain.

Steep slopes: Steep slopes can accelerate the process of soil erosion by rain. When rainwater flows down a steep slope, it gains momentum and power, increasing the force with which it hits the soil. This force can dislodge soil particles and carry them away, leading to erosion. Therefore, steep slopes can cause soil erosion by rain.

Aridity: Aridity refers to dryness or a lack of moisture. In arid regions, rainfall is limited, and the soil may be dry and less prone to erosion caused by rain. The lack of significant rainfall reduces the chances of soil particles being dislodged by raindrops or carried away by runoff, making aridity a factor that does not cause soil erosion by rain.

In conclusion, all the options except aridity can contribute to soil erosion by rain. Tropical rainstorms, scanty vegetation, and steep slopes can all increase the likelihood of soil erosion. However, in arid regions where there is a lack of moisture, the risk of soil erosion caused by rain is reduced.

Which of the following is not correct about the great circle?

Answer Details

A great circle is a type of circle that can be formed on the Earth's surface. It is called "great" because it has the same radius as the Earth. Let's go through each statement and determine which one is not correct: 1. The statement says that the Equator is a Great Circle among the latitudes. This statement is **correct**. The Equator is indeed a great circle because it is a circle that cuts the Earth in half, dividing it into the Northern Hemisphere and the Southern Hemisphere. 2. The statement says that the Greenwich Meridian and the International Date Line are the only lines of latitude forming a Great Circle. This statement is **not correct**. The Greenwich Meridian and the International Date Line are not lines of latitude; they are lines of longitude. A great circle can be formed by any line of latitude, not just the Greenwich Meridian and the International Date Line. 3. The statement says that the Great Circle divides the Earth into two equal spheres. This statement is **not correct**. The Great Circle does divide the Earth, but not into equal spheres. Instead, it divides the Earth into two hemispheres, which are halves of the Earth. 4. The statement says that the center of the Great Circle is also the center of the Earth. This statement is **not correct**. The center of a great circle does not necessarily coincide with the center of the Earth. The center of a great circle is simply the midpoint of the circle, which can be anywhere on the Earth's surface. To summarize: - Statement 1 is correct. - Statement 2 is not correct. - Statement 3 is not correct. - Statement 4 is not correct. Therefore, the statement that is not correct about the great circle is statement 2, which claims that the Greenwich Meridian and the International Date Line are the only lines of latitude forming a Great Circle.

The difference in time between two longitudes is approximately

Answer Details

The difference in time between two longitudes is approximately 4 minutes.
To understand this, let's first understand what longitudes are. Longitudes are imaginary lines that run vertically around the Earth, from the North Pole to the South Pole. They help to identify specific locations on the Earth's surface.
Now, the Earth takes 24 hours to complete one full rotation around its axis. This rotation results in the sun appearing to rise and set in different parts of the world at different times. This is what gives us our concept of time zones.
By convention, the Earth is divided into 24 time zones, each covering approximately 15 degrees of longitude. Each time zone represents an hour of difference in time.
So, if we do the math, we can calculate that with 360 degrees (the full circumference of the Earth) divided by 24 time zones, each time zone covers 15 degrees of longitude. This means that for every 15 degrees of longitude you travel east or west, there is a time difference of about one hour.
Since each time zone represents one hour and there are 60 minutes in an hour, we can calculate that the time difference for every 1 degree of longitude is approximately 4 minutes (60 minutes divided by 15 degrees).
Therefore, the correct answer is 4 minutes

A slope is said to be even when the contours are

Answer Details

A slope is said to be even when the contours are **equally placed**. This means that the contours are evenly spaced apart from each other. When the contours are evenly spaced, it indicates that the slope of the land is relatively consistent throughout the area. Imagine looking at a map or a cross-section of a hill or mountain. Contours are the lines on the map that connect points of the same elevation. They give us a visual representation of how steep or gentle the slope is at any given point. When the contours are evenly spaced, it means that the difference in elevation between each contour line is consistent. This indicates that the slope is gradual and not too steep. For example, if we have contour lines that are evenly spaced apart by 10 meters, it means that the slope of the land is changing by approximately 10 meters in height with each contour line. On the other hand, if the contours are irregularly spaced, it means that the slope is varying more dramatically. This can indicate areas of steep cliffs or sudden changes in elevation. In summary, an even slope is characterized by **equally placed** contours, indicating a gradual and consistent change in elevation.
