Study the table given which shows the mean climatic conditions of station Q and answer the questions.

Bayanin Amsa

Based on the given mean climatic conditions, the station has a "Cool Temperate" climate. This is because the average temperature during the warmest month (July) is 19°C, which is below the threshold for a "Warm Temperate" or "Mediterranean" climate. Additionally, the average temperature during the coldest month (January) is -11°C, which is characteristic of a "Cool Temperate" or "Cold Temperate" climate. The amount of precipitation throughout the year is moderate, with the wettest month being July with 71mm of rainfall.

The feature is one or the land forms associated with_________

Bayanin Amsa

The feature associated with river erosion is valleys. River erosion occurs when a river's fast-moving water cuts into its riverbed and banks, causing the river to widen and deepen over time. This process creates steep-sided valleys that are wider at the bottom than at the top. The riverbed and banks are constantly being reshaped by the erosive forces of the water, which carry away sediment and rocks. Over time, the river's course may change as it continues to erode and deposit material, carving new valleys and leaving behind a signature of its past path in the form of terraces.

In which of the following rock types is petroleum mainly found?

Bayanin Amsa

Petroleum is mainly found in sedimentary rocks. Sedimentary rocks are formed from the accumulation and cementation of sediments, which can include organic matter such as dead plants and animals. Over time, this organic matter can become buried and subjected to heat and pressure, which can transform it into petroleum through a process called diagenesis. Petroleum is a fossil fuel that is composed of hydrocarbons, which are molecules made up of carbon and hydrogen atoms. The organic matter in sedimentary rocks that forms petroleum is usually derived from marine plants and animals that died and sank to the bottom of the ocean. Over time, these organic remains can be buried by layers of sediment, and the heat and pressure from the overlying rocks can cause them to be transformed into petroleum. While it is possible for petroleum to be found in other types of rocks, such as metamorphic rocks that have undergone extreme heat and pressure, sedimentary rocks are by far the most common type of rock that contains petroleum. This is because the process of petroleum formation requires the accumulation and burial of organic matter, which is most likely to occur in sedimentary environments such as oceans, lakes, and swamps.

A mercury barometer is used for measuring_________

Bayanin Amsa

A mercury barometer is used for measuring atmospheric pressure. Atmospheric pressure is the force exerted by the weight of air molecules in the atmosphere. It is an important parameter that affects weather patterns and other natural phenomena. A mercury barometer consists of a long glass tube filled with mercury and inverted into a dish of mercury. The mercury in the tube rises or falls depending on the atmospheric pressure. When the atmospheric pressure is high, the weight of the air above the barometer pushes down on the surface of the mercury in the dish, forcing the mercury in the tube to rise. Conversely, when the atmospheric pressure is low, the weight of the air above the barometer is less, and the mercury in the tube falls. By measuring the height of the mercury column in the tube, the atmospheric pressure can be determined. The standard unit of atmospheric pressure is the Pascal (Pa), but barometric pressure is often measured in units of millimeters of mercury (mmHg) or inches of mercury (inHg). In summary, a mercury barometer is a device used to measure atmospheric pressure by observing the height of a column of mercury in a glass tube.

Which of the following countries has the least potential for the production of steel?

Bayanin Amsa

Among the options given, Cuba has the least potential for the production of steel. Cuba is a small island country in the Caribbean with a limited supply of natural resources, including iron ore and coal, which are essential raw materials for steel production. Cuba's iron reserves are low-quality and require significant processing to be suitable for steelmaking. Additionally, Cuba has limited access to modern steelmaking technology and expertise, which further restricts its potential for steel production. On the other hand, India, Japan, and Germany have significant potential for steel production. India is one of the world's largest producers of steel, with abundant iron ore reserves and a highly skilled workforce. Japan and Germany are also major players in the global steel industry, with advanced technology and ample access to raw materials.

The two most important factors which account for the pattern of population distribution in West Africa are

Bayanin Amsa

Physical conditions determine the population distribution in Africa. The topography of an area, how favourable it is determine population distribution. People tend to move from a place to another if the condition is not favourable. Nomads for example move their cattles around for pastures to graze.

A river transport its load through the following processes except_________

Bayanin Amsa

The river transports its load through three main processes: solution, traction, and suspension. Plucking is not a process by which a river transports its load. Solution is the process by which the river dissolves soluble minerals such as calcium and transports them in solution. Traction is the process by which larger and heavier particles such as boulders and pebbles are rolled or dragged along the riverbed. Suspension is the process by which smaller and lighter particles such as silt and clay are carried along in the flowing water. Plucking, on the other hand, is a process by which glaciers transport their load. It occurs when the glacier freezes onto rocks and then plucks them out as the glacier moves. This process is not applicable to rivers as they do not have the capability to freeze onto rocks and pluck them out.

In which of the following countries is cotton growing under irrigation the mainstay of the agricultural economy?

Bayanin Amsa

Cotton growing under irrigation is the mainstay of the agricultural economy in Sudan. Sudan is one of the largest producers of cotton in Africa and the world, and cotton farming is a major part of its agricultural economy. The country has a long history of growing cotton, with the industry dating back to the early 20th century. Cotton farming in Sudan is mainly done under irrigation due to the arid climate in most parts of the country. The irrigated areas for cotton farming are mainly found in the central and eastern regions of the country, such as the Gezira Scheme, which is one of the largest irrigation projects in the world. Cotton is a major export commodity for Sudan, and the industry employs a significant portion of the country's population. The government has made efforts to promote and support the cotton industry, with initiatives such as providing subsidies to farmers and investing in research and development to improve cotton production and quality. In summary, cotton growing under irrigation is the mainstay of the agricultural economy in Sudan, due to its favorable climate for cotton farming, long history of cotton production, and significant export earnings from the cotton industry.

Bayanin Amsa

A fold mountain is a type of land-form that is associated with large scale orogeny. In simple terms, orogeny is the process of mountain building, which occurs when two tectonic plates collide and push up the land between them. This process causes the rock layers to bend, fold and become uplifted, creating a fold mountain. Examples of fold mountains include the Rocky Mountains in North America and the Himalayas in Asia.

One of the following is associated with wind deflation in arid region_________

Bayanin Amsa

Deflation is an action of wind when it picks up or remove loose particles from an area and leaves a denuded surface covered with coarse material too large for wind transport. The most noticeable results of deflation in some places are shallow depressions called blowouts

Which of the following is not a proof to show that the earth is spherical in shape?

Bayanin Amsa

The option that is not a proof to show that the Earth is spherical in shape is "twilight and dawn." While sunrise, sunset, ships visibility, and lunar eclipse are all evidence that supports the idea that the Earth is a sphere, twilight and dawn are not necessarily proof of this shape. Twilight and dawn occur when the Sun is just below the horizon and its light is scattered by the Earth's atmosphere, creating a soft, diffuse light. While this phenomenon is consistent with the idea that the Earth is a sphere, it is not unique to this shape and could also occur on other types of celestial bodies. In contrast, sunrise and sunset occur because the Earth's spherical shape causes the Sun's light to be blocked from certain parts of the planet as it rotates on its axis. Ships visibility and lunar eclipses are also consistent with the idea that the Earth is a sphere because they demonstrate the way that a sphere can obstruct light and shadow.

Study the map and answer the question. The bearing of Jata from Adaba is approximately

Bayanin Amsa

To determine the approximate bearing of Jata from Adaba using the map, we need to look at the compass rose and use the scale provided. Looking at the compass rose, we can see that North is pointing towards the top of the map. To find the bearing of Jata from Adaba, we need to draw a straight line from Adaba to Jata on the map, and then measure the angle between this line and North using a protractor. Measuring this angle, we can see that it is approximately 21 degrees. Therefore, the bearing of Jata from Adaba is approximately 21°. Note that this is an approximation since we are using a ruler and protractor on a printed map, which may not be completely accurate. Additionally, the actual bearing of Jata from Adaba may differ slightly depending on the specific route taken.

Along which latitude will be the day time be longest on Christmas day?

Bayanin Amsa

All the following are environmental hazards except___________

Bayanin Amsa

The environmental hazard among the given options that is not included is afforestation. Afforestation refers to the process of planting trees in an area where there was no forest, or the forest has been destroyed, and it is typically seen as a positive action for the environment. On the other hand, the other three options are environmental hazards that can have negative impacts on people and the environment. Flooding, for example, can lead to property damage, displacement of people, and loss of life. Vulcanicity, which refers to the movement of magma and volcanic activity, can result in the release of toxic gases, destruction of property, and loss of life. Deforestation, which is the clearing of forests for various human activities, can cause soil erosion, loss of biodiversity, and contribute to climate change.

Lines joining places with same mean annual rainfall are called___________

Bayanin Amsa

Lines joining places with the same mean annual rainfall are called isohyets. Isohyets are lines drawn on a map connecting points that receive the same amount of rainfall in a year. The word "isohyet" comes from the Greek words "iso" meaning "equal" and "hyetos" meaning "rain". These lines help us understand the patterns and distribution of rainfall over a certain area, and can be useful for various purposes such as agriculture, water management, and meteorology.

The plains formed when the slopes of mountains are worn back in arid and semi-arid regions my mechanical weathering is called_______

Bayanin Amsa

The plains formed when the slopes of mountains are worn back in arid and semi-arid regions by mechanical weathering is called "Pediplains". Pediplains are a type of plain that form as a result of the gradual erosion and weathering of mountains and hills. They typically occur in arid and semi-arid regions where there is little vegetation to protect the land from erosion. Over time, as the wind, rain, and other natural forces wear away at the mountain slopes, sediment is carried downhill and deposited on the surrounding plain. This sediment can be made up of rocks, sand, and soil, and can create a relatively flat and gently sloping plain that extends out from the base of the mountain. Unlike other types of plains, such as alluvial plains or outwash plains, which are formed by water deposition, pediplains are formed by the mechanical weathering and erosion of rock and soil. They are typically found in regions where there is little precipitation and where the climate is dry and hot, which can help to speed up the weathering process.

Which of the following rocks is composed of the skeletons of microscopic sea plants and animals?

Bayanin Amsa

The rock composed of the skeletons of microscopic sea plants and animals is called "Chalk". Chalk is a soft, white, porous sedimentary rock that is formed from the remains of tiny marine organisms called coccolithophores. These microscopic creatures have hard shells made of calcium carbonate, and when they die, their shells accumulate on the ocean floor. Over time, these accumulations can become compressed and cemented together, forming the soft rock we know as chalk. Chalk is often found in areas that were once covered by shallow seas, such as in the cliffs of southern England. It has many uses, including as a writing surface, in construction, and as a natural fertilizer. Its softness and white color also make it a popular material for art, such as in the creation of chalk drawings.

Which of these hazard would most like result directly from deforestation?

Bayanin Amsa

Deforestation is the clearing of trees and other vegetation in a forested area. One of the most likely hazards that can result directly from deforestation is soil erosion. When trees are cut down, the roots that held the soil in place are also removed, leaving the soil exposed and vulnerable to erosion by wind and rain. With no tree cover to protect the soil, rainwater can wash away the topsoil, leading to soil erosion. This process can cause the soil to become less fertile, which can make it difficult for plants to grow and can ultimately lead to desertification. Additionally, deforestation can also lead to changes in the water cycle, which can result in decreased water availability, increased flooding, and other forms of water pollution. However, these hazards are less directly linked to deforestation than soil erosion.

Which of the following is not a form of mass movement?

Bayanin Amsa

The answer is "earthquake" as it is not a form of mass movement. Mass movement refers to the process by which large amounts of soil, rock, and other debris move down a slope under the influence of gravity. Landslides, rockslides, and talus creep are all examples of mass movement. An earthquake, on the other hand, is a sudden shaking of the earth's surface caused by the movement of tectonic plates. While earthquakes can cause landslides and other types of mass movement, the earthquake itself is not a form of mass movement. Instead, it is a geological event that can trigger mass movement in the surrounding area.

How long does it take the mercury to make a complete revolution?

Bayanin Amsa

The answer is 88 days. Mercury is the planet closest to the Sun, and it orbits around the Sun at a very fast pace. It takes approximately 88 Earth days for Mercury to make one complete orbit around the Sun. This means that Mercury completes about 4 orbits in the time it takes Earth to complete 1 orbit. Because of its fast orbit and close proximity to the Sun, Mercury experiences extreme temperature variations, with temperatures ranging from over 800 degrees Fahrenheit during the day to -290 degrees Fahrenheit at night.

If the distance between two places on a map is 2cm, while the distance on land is 4km, the scale of the map is

Bayanin Amsa

The scale of a map is the ratio of the distance on the map to the actual distance on land. It is usually written as a fraction, like 1:100,000, where the first number represents the distance on the map and the second number represents the corresponding distance on land. To find the scale of the map in question, we need to divide the actual distance on land (4km) by the distance on the map (2cm). First, we need to convert 4 km to cm: 4 km = 4 x 10^3 m = 4 x 10^3 x 100 cm = 4 x 10^5 cm Now, we divide the actual distance on land (4 x 10^5 cm) by the distance on the map (2 cm): (4 x 10^5 cm) / (2 cm) = 2 x 10^5 So the scale of the map is 1 : 2 x 10^5, which is equivalent to 1:200,000.

What type of climate has the station___________

Bayanin Amsa

Climate is the weather conditions prevailing in an area in general or over a long period.

Organic components of the soil include all the following except_______

Bayanin Amsa

The organic components of the soil include microorganisms, humus, and animal remains. The correct answer, therefore, is "rock pedestal." Rock pedestal, also known as bedrock, is a non-organic component of the soil. It is the solid, underlying layer of rock that makes up the Earth's crust. Bedrock does not contain any organic material, and it does not contribute to the fertility of the soil. On the other hand, the organic components of soil are essential for healthy plant growth. Microorganisms break down organic matter into nutrients that plants can absorb, while humus provides a rich source of nutrients for plant growth. Animal remains, such as dead insects or animal waste, can also provide organic material for the soil. In summary, while microorganisms, humus, and animal remains are all examples of organic components of soil, rock pedestal is a non-organic component and does not contribute to the fertility of the soil.

Bayanin Amsa

Use the diagram below to answer the question. The feature is one of the landforms associated with

Bayanin Amsa

The feature in the diagram is a sand dune, which is a landform associated with wind deposition. Sand dunes are formed when wind carries sand particles and deposits them in a particular location, creating a mound of sand. Over time, as the wind continues to blow, the sand dune may shift or change in shape. Sand dunes can be found in deserts, on beaches, and in other areas with high wind activity.

Lines joining places of equal sunshine duration on maps are__________

Bayanin Amsa

The lines joining places of equal sunshine duration on maps are called Isohel. Isohel is a type of contour line that connects all the points on a map that receive the same amount of sunlight in a given period, usually a day or a year. These lines are similar to contour lines on a topographic map that connect points of equal elevation. Isohels are used to show areas with similar amounts of sunshine and can be used to analyze patterns in climate and weather. For example, isohel maps can help identify areas with higher or lower amounts of sunlight and help to plan agriculture, solar power generation, and other activities that depend on sunlight.
