What is the population density of a country with a total population of 140,000,000 and a total land area of 500,000 (\Km^2\)?

Antwoorddetails

To calculate the population density of a country, we need to divide the total population of the country by its total land area. In this case, we are given that the total population of the country is 140,000,000 and the total land area is 500,000 km². To find the population density, we divide the population by the land area: Population density = Total population / Total land area Population density = 140,000,000 / 500,000 = 280 persons per km². Therefore, the correct answer is **280 persons per km²**.

Which of the following rocks is produced by the solidification of magna within the earth crust

Antwoorddetails

The rock that is produced by the solidification of magma within the Earth's crust is called **plutonic rock**. Plutonic rocks are also known as intrusive rocks. Magma is molten rock that is found beneath the Earth's surface. When this magma cools down slowly, it solidifies and crystalizes within the Earth's crust, forming plutonic rocks. This slow cooling process allows for the formation of large mineral crystals within the rock. One key characteristic of plutonic rocks is that they have a coarse grain texture. This means that the mineral crystals within the rock are visible to the naked eye. Examples of plutonic rocks include granite, diorite, and gabbro. In contrast, **extrusive rocks** are formed from lava that cools quickly on the Earth's surface. When lava erupts from a volcano and cools rapidly, it forms extrusive rocks. These rocks, such as basalt and pumice, have a fine-grained texture because the fast cooling does not allow for the growth of large mineral crystals. On the other hand, **sedimentary rocks** are formed from the compaction and cementation of sediments (such as sand, silt, and clay) that have been deposited by water, wind, or ice. Sedimentary rocks, like sandstone and limestone, often contain fossils and layers. Lastly, **metamorphic rocks** are formed by the transformation of existing rocks due to high temperature and pressure deep within the Earth's crust. Examples of metamorphic rocks include marble and quartzite. To summarize, plutonic rocks are produced by the slow solidification of magma within the Earth's crust, resulting in coarse-grained rocks with visible mineral crystals.

The difference in time between two longitudes is approximately

Antwoorddetails

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

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

Antwoorddetails

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 has the highest salinity?

Antwoorddetails

The Dead Sea has the highest salinity among the given options. Salinity refers to the amount of salt dissolved in water. In other words, it is a measure of the saltiness of the water. The Dead Sea is located between Israel and Jordan, and it is actually not a sea but a saltwater lake. What makes the Dead Sea unique is its extremely high salt concentration. The water in the Dead Sea is about 10 times saltier than sea water. There are several reasons why the Dead Sea has such high salinity. Firstly, it is located in a region with a very hot and dry climate, which means that water evaporates quickly. As the water evaporates, the salt gets left behind, increasing the overall concentration of salt in the lake. Secondly, the Dead Sea is landlocked, which means it does not have an outlet or a flow of water that can dilute the salt concentration. Unlike the Mediterranean Sea or the Red Sea, which are connected to the global ocean system, the Dead Sea is a closed basin. As a result, the salt that enters the lake stays there and continues to accumulate over time. Lastly, the Dead Sea region is known for its rich mineral deposits, including salts. These minerals get washed into the lake through rivers and streams, further contributing to the high salinity of the water. In summary, the Dead Sea has the highest salinity among the given options due to its evaporation, lack of connection to the global ocean system, and the presence of mineral deposits. This high salinity creates a unique environment where floating becomes effortless and leads to the formation of salt crystals along the shores.

Antwoorddetails

The instrument used to measure the duration of sunshine is called the **campbell-stokes recorder**. This instrument is specifically designed to measure the amount of sunlight received at a particular location over a given period of time. The campbell-stokes recorder consists of a glass sphere that is mounted in a metal frame. This sphere acts as a lens, focusing the sunlight onto a specially designed card or paper underneath. The card or paper is positioned in such a way that it is slightly above the focal point of the lens. When sunlight passes through the lens and focuses on the card, it causes the card to heat up. As a result, a burn mark or a scorch is left on the card. By measuring the length of the burn mark, we can determine the duration of sunshine. The campbell-stokes recorder is widely used in meteorology and climatology to monitor and document the amount of sunshine received in a given area. It is a simple and effective instrument that provides valuable data for studying weather patterns, climate change, and solar energy potential. In conclusion, the instrument used to measure the duration of sunshine is the campbell-stokes recorder, which uses a glass sphere to focus sunlight onto a card or paper and measures the length of the resulting burn mark.

Antwoorddetails

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.

Water vapour is turned into water droplets by the process of

Antwoorddetails

Water vapour is turned into water droplets by the process of **condensation**. Condensation occurs when water vapor, which is in the gaseous state, comes into contact with a cool surface or cool air. When the temperature of the water vapor decreases, the water molecules slow down and move closer together. This causes the water vapor to transform into liquid water, forming water droplets. To understand this process better, think of a glass of cold water on a warm day. As the warm air comes into contact with the cold surface of the glass, the water vapor in the air loses heat energy and condenses into water droplets on the outside of the glass. This is why you observe water droplets forming on the glass. Similarly, when warm, moist air rises and comes into contact with cooler air in the atmosphere, or when it encounters cool surfaces such as windows, mirrors, or grass in the early morning, condensation occurs, and water droplets are formed. In summary, condensation is the process where water vapor changes from a gaseous state to a liquid state by cooling down, resulting in the formation of water droplets.

In conclusion, the broad-leafed evergreen and dense equatorial forest of the Amazon basin is known as selvas. It is a unique and important ecosystem with immense biodiversity and crucial ecological functions.

A slope is said to be even when the contours are

Antwoorddetails

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.

Which of the following distinguishes rotation from revolution?

Antwoorddetails

The statement that distinguishes rotation from revolution is that "The earth rotates on its axis while it revolves around the sun in an elliptical orbit." Rotation refers to the spinning of an object around its own axis. In the case of the Earth, it rotates on an imaginary line called its axis. This rotation is responsible for various phenomena like the change between day and night. As the Earth rotates, different parts of it are exposed to the Sun's light, creating the cycle of day and night. Revolution, on the other hand, refers to the movement of an object around another object in space. In the case of the Earth, it revolves around the Sun in an elliptical orbit. This revolution takes approximately 365.25 days to complete, which gives us a year. So, to summarize, rotation refers to the spinning of an object on its axis, causing phenomena like day and night. Revolution refers to the movement of an object around another object in space, giving us the concept of a year.

Which of the following is not a process of chemical weathering?

Antwoorddetails

Chemical weathering is a process in which the chemical composition of rocks and minerals is altered due to exposure to certain substances or environmental conditions. It plays a significant role in the breakdown and decomposition of rocks over time. Out of the options given, **frost action** is not a process of chemical weathering. Frost action, also known as freeze-thaw weathering, refers to the physical breakdown of rocks caused by repeated freezing and thawing of water within the rock fractures. It is a type of physical weathering, not chemical. Now let's briefly explain the other three options and how they relate to chemical weathering: 1. **Hydrolysis** is a chemical process in which water reacts with minerals in the rock, leading to their breakdown. Minerals such as feldspar and mica are commonly affected by hydrolysis. Water molecules interact with these minerals, causing them to break down into new minerals or dissolved ions. This process weakens the rock's structure and contributes to its gradual degradation. 2. **Oxidation** is another chemical process that occurs when certain minerals in rocks react with oxygen in the presence of water or air. This reaction causes the minerals to undergo a chemical change, resulting in the formation of new compounds. For example, when iron minerals in rocks come into contact with oxygen, they can oxidize and form iron oxide, more commonly known as rust. This process weakens the rock and makes it more susceptible to further weathering. 3. **Carbonation** is the chemical weathering process associated with the dissolution of carbon dioxide in water, forming carbonic acid. This acid reacts with minerals such as calcium carbonate (present in rocks like limestone and marble), leading to their dissolution. Carbonation is a common process in regions with a high concentration of carbon dioxide in the atmosphere or in areas where water with dissolved carbon dioxide comes into contact with rocks. In conclusion, **frost action** is not a process of chemical weathering but rather a form of physical weathering. Hydrolysis, oxidation, and carbonation, on the other hand, are all examples of chemical weathering processes that contribute to the degradation and alteration of rocks over time.

A block mountain is formed as a result of

Antwoorddetails

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.

Therefore, the answer to the question is that **June** is the month of the year with the highest temperature in station Z, as evidenced by the table.

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

Antwoorddetails

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.

**A major function performed by rural settlements is agriculture.** Rural settlements are areas where people live in small towns or villages, often located outside of cities. These settlements are mainly involved in agricultural activities, which means they are focused on farming and cultivating crops. Agriculture is an essential function of rural settlements because it provides food and other resources for the people living there. Farmers grow various crops such as wheat, rice, corn, and vegetables, which are then consumed by the community or sold to nearby towns and cities. In addition to crops, rural settlements may also have livestock like cows, sheep, or chickens, which provide meat, eggs, and dairy products. Agriculture is not only important for providing food, but it also contributes to the local economy. When farmers sell their products, it generates income for the community, allowing them to purchase other necessities and services. Furthermore, agriculture helps to sustain the environment in rural areas. Farmers often practice sustainable farming techniques, such as crop rotation and the use of organic fertilizers, to maintain soil fertility and prevent the depletion of natural resources. Overall, agriculture is a vital function of rural settlements as it supports the livelihoods of the residents, provides food and resources, contributes to the local economy, and helps sustain the environment.
