Bayanin Amsa

River regime is best described as the seasonal variation in the volume of water in a river. It refers to the pattern of the flow of water in a river over the course of a year, which is affected by changes in temperature, precipitation, and other factors. The river regime describes the variations in the discharge, or the amount of water flowing in the river, over time. This variation can be influenced by several factors, such as the amount and timing of rainfall, the amount of snowmelt, and the presence of dams or other structures that regulate the flow of the river. In some regions, rivers have a well-defined regime with distinct seasons of high and low water, while in other regions, the regime may be less predictable due to more erratic weather patterns. Understanding the river regime is important for managing water resources, predicting floods, and maintaining ecosystems that depend on the natural flow of rivers.

Bayanin Amsa

The coastal regions of Sierra Leone record an annual rainfall of over 4,000 mm. Sierra Leone is a country located in West Africa, and its climate is generally tropical, with high temperatures and high humidity. The amount of rainfall that a place receives is determined by a number of factors, including its location and topography. The coastal regions of Sierra Leone are characterized by a dense forest and a humid climate, which is influenced by the Atlantic Ocean. The prevailing winds from the ocean bring moisture and result in high levels of rainfall. This region receives an annual rainfall of over 4,000 mm, which is one of the highest levels of rainfall in the world. The high rainfall is beneficial for agriculture, as it provides the necessary moisture for crops to grow. However, it can also result in flooding and landslides, which can be hazardous for the people living in the region. In summary, the coastal regions of Sierra Leone receive an annual rainfall of over 4,000 mm, which is a result of the region's location and its proximity to the Atlantic Ocean.

These are landforms producing agent except

Bayanin Amsa

Out of the given options, storms are not a landform producing agent. Landforms are natural features on the Earth's surface, such as mountains, valleys, and plains, that are created over long periods of time through the actions of various agents. These agents include natural forces such as water, wind, ice, and gravity. Waves, rivers, and glaciers are all agents that can shape the Earth's surface over time. Waves can erode coastlines and create features like sea cliffs and sea caves. Rivers can carve out valleys and canyons through erosion and transport sediment downstream. Glaciers can also erode and transport sediment, as well as create features such as moraines and U-shaped valleys. On the other hand, storms are not an agent that shapes the Earth's surface in a significant way. Storms are short-lived weather events that can cause erosion and deposition in some areas, but they are not powerful enough to create significant landforms on their own. However, storms can interact with other landforming agents like rivers and waves, exacerbating their effects and creating more dramatic changes to the landscape.

The type of water left in the soil after excess water has been drained off, following heavy rainfall is known as

Bayanin Amsa

The type of water left in the soil after excess water has been drained off following heavy rainfall is known as field capacity. Field capacity refers to the amount of water that the soil can hold after excess water has drained away and the soil particles have become saturated. This water is held in the soil by a combination of gravity and the attraction between water molecules and soil particles. In other words, field capacity is the point at which the soil is neither too wet nor too dry, and it is the maximum amount of water that can be stored in the soil and still be available for plants to use.

In Nigeria, which of the following vegetation zones is best known for timber exploitation?

Bayanin Amsa

The vegetation zone in Nigeria that is best known for timber exploitation is the rain forest. The rain forest is a vegetation zone characterized by a dense growth of tall trees and high rainfall, which is conducive to the growth of large trees suitable for timber production. This type of vegetation is found in the southern part of Nigeria, particularly in states such as Cross River, Akwa Ibom, Rivers, and Delta. In these areas, there are many timber companies that engage in the logging and processing of timber from the rain forest. The timber industry is an important sector of the Nigerian economy, as timber is used for a variety of purposes such as construction, furniture making, and paper production. However, it is important to note that unsustainable logging practices can lead to deforestation and habitat loss, which can have negative impacts on biodiversity and the ecosystem. Therefore, it is important to ensure that logging activities are carried out in a sustainable manner, with measures taken to preserve the forest and its biodiversity for future generations.

Nigeria's major export commodity is petroleum, also known as crude oil. Petroleum is a fossil fuel that is formed from the remains of plants and animals that died millions of years ago. It is a valuable resource that is used in a wide range of applications, including transportation, power generation, and manufacturing. In Nigeria, petroleum was discovered in the 1950s, and it has since become the country's major export commodity, accounting for a significant portion of the country's revenue. Nigeria is one of the largest oil producers in Africa and one of the top oil exporters in the world. The oil industry has had a significant impact on Nigeria's economy, providing employment opportunities and contributing to the country's economic growth. However, there have also been concerns about the environmental impact of oil exploration and the management of the revenue generated from the industry. In summary, Nigeria's major export commodity is petroleum, which is a valuable resource used in various industries. The discovery and production of oil have had a significant impact on Nigeria's economy, but there are also challenges and concerns associated with the industry.

These are areas of crude oil production in Nigeria except

The following are volcanic mountains except

Bayanin Amsa

Monadnock of the USA is not a volcanic mountain. Volcanic mountains are formed when molten rock (magma) rises to the surface and erupts, building up layer upon layer of solidified rock and ash. Some examples of well-known volcanic mountains include Cotopaxi in Ecuador, Mount Fuji in Japan, and Mount Merapi in Sumatra. Monadnock, on the other hand, is a type of mountain called a monadnock or inselberg, which means "island mountain." These are isolated hills or mountains that rise abruptly from surrounding flat or gently sloping terrain and are often made of hard, resistant rock that has not been worn away by erosion. Monadnock is a monadnock and was formed through the uplift of a large mass of rock and the subsequent erosion of the surrounding land.

Which of the following processes leads to the loss of carbon from the air

Bayanin Amsa

One of the following surveying instruments is used to set out lines at right angles to the main chain line

Bayanin Amsa

The surveying instrument used to set out lines at right angles to the main chain line is an optical square. An optical square is a simple, yet precise surveying instrument that consists of two mirrors that are set at exactly 90 degrees to each other. It is used to establish perpendicular lines or right angles to the main chain line during the surveying process. The instrument is set up by placing it on the ground with one mirror facing down the main chain line and the other mirror facing at right angles to the main chain line. To use the optical square, a surveyor would first set up the main chain line using a steel band or another measuring instrument. Once the main chain line has been established, the optical square is set up and aligned with the main chain line. The mirror facing down the main chain line reflects the view of the surveyor along the line, while the other mirror reflects the view at right angles to the main chain line. This allows the surveyor to set out lines at right angles to the main chain line with a high degree of accuracy. In summary, the optical square is a surveying instrument used to set out lines at right angles to the main chain line by reflecting views along the main chain line and at right angles to it.

Where the salinity of an ocean is high;

Bayanin Amsa

When the salinity of an ocean is high, the ocean water becomes more dense. This dense water tends to sink towards the bottom of the ocean and flow along the ocean floor towards areas where the salinity is lower. So, the correct answer is: the ocean water is dense and creeps at the bottom of the ocean towards low salinity areas.

The feature marked Y on the map is?

Bayanin Amsa

Which of the following is a sedimentary rock.

Bayanin Amsa

Shale is a sedimentary rock. Sedimentary rocks are formed from layers of sediment, such as dead plants and animals, sand, or mud, that have been compacted and cemented together over time. Shale is a fine-grained sedimentary rock that forms from the compression of clay and silt. It is usually dark in color and can be easily split into thin layers. Marble, on the other hand, is a metamorphic rock, which means it was formed from the alteration of an existing rock, often through heat, pressure, and chemical processes. It is a dense, crystalline rock that is prized for its beauty and used in construction and sculpture. Graphite is a naturally occurring form of carbon and is not a rock. Schist is a metamorphic rock that forms from the alteration of existing rocks, often through heat, pressure, and chemical processes. It is characterized by its foliated texture, with flat, sheet-like minerals that are aligned in a particular direction.

If the scale of two maps are (a;1:100,000 and b;1:400,000) what is the ground distance if the distance between two towns on the maps is 10cm

Bayanin Amsa

To determine the ground distance between the two towns on the map, we need to use the scale of the map. The scale tells us how many units of distance on the map (in this case, centimeters) correspond to one unit of ground distance (in this case, kilometers). For map a with a scale of 1:100,000, 1 centimeter on the map represents 100,000 centimeters or 1 kilometer on the ground. Therefore, 10 centimeters on the map represents 10 x 1 kilometer = 10 kilometers on the ground. For map b with a scale of 1:400,000, 1 centimeter on the map represents 400,000 centimeters or 4 kilometers on the ground. Therefore, 10 centimeters on the map represents 10 x 4 kilometers = 40 kilometers on the ground. So the correct answer is 10km, 40km.

Bayanin Amsa

Urban settlements often supply manufactured goods to rural settlements. Manufactured goods are products that are made using raw materials and processes that transform these materials into finished products. Urban areas often have a higher concentration of factories and industries that produce these manufactured goods, which are then supplied to rural areas. This allows rural residents to access products that they may not be able to produce themselves, such as electronics, household appliances, and other consumer goods. By supplying these goods, urban settlements play an important role in supporting the economic development of rural areas.

Bayanin Amsa

Which of the following rocks is organically formed?

Bayanin Amsa

Coal is the rock that is organically formed. Coal is formed from the remains of ancient plants and trees that died millions of years ago. Over time, these organic materials were buried under layers of sediment and rock, which subjected them to intense pressure and high temperatures. This process caused the organic matter to transform into coal, a black or brown rock that is primarily composed of carbon. In contrast, Gypsum, Grit, and Shale are all rocks that are formed through inorganic processes. Gypsum is formed from the evaporation of saline water, grit is a sandstone that is formed from the accumulation of sand particles, and shale is formed from the accumulation of mud and silt. In summary, coal is the only rock that is formed through organic processes, while gypsum, grit, and shale are formed through inorganic processes.

Bayanin Amsa

Which of the following is an effect of the earth's revolution?

Bayanin Amsa

One effect of the earth's revolution is that it determines a year. The earth takes approximately 365.24 days to complete one orbit around the sun, which is known as a year. As the earth moves around the sun, it also causes changes in the amount of sunlight that different parts of the planet receive, which in turn affects the seasons. The tilt of the earth's axis also plays a role in determining the seasons. As the earth moves in its orbit, different parts of the planet are tilted towards or away from the sun, which causes the variations in the amount of daylight and darkness we experience throughout the year. Therefore, while day and night, dawn and twilight, and apparent sunrise and sunset are also effects of the earth's rotation, the revolution primarily determines a year.

On maps, lines drawn to join all places in the ocean having equal degree of salinity are called

Bayanin Amsa

On maps, lines drawn to join all places in the ocean having equal degree of salinity are called isohalines. Isohalines are similar to contour lines on topographic maps that join all points of equal elevation. However, instead of elevation, isohalines connect all points on a map that have the same salinity in the ocean. Ocean salinity is a measure of the amount of salt dissolved in a given amount of seawater. The salinity of ocean water varies depending on several factors, such as temperature, evaporation, and precipitation. By drawing isohalines on maps, scientists can visualize the patterns of salinity distribution in the ocean and study how it changes over time. The term "isohaline" comes from the Greek word "iso" meaning equal and "haline" meaning salt, so it literally means "equal salt."

Bayanin Amsa

The difference between the hottest and coldest daily temperature for a particular day is called the diurnal range of temperature. A combined maximum and minimum thermometer records both the highest and lowest temperatures that occur during a given period, typically a day. The highest temperature recorded is the maximum daily temperature, and the lowest temperature recorded is the minimum daily temperature. The diurnal range of temperature is the difference between these two values, indicating how much the temperature fluctuated over the course of the day. For example, if the highest temperature recorded was 30 degrees Celsius and the lowest temperature recorded was 15 degrees Celsius, then the diurnal range of temperature for that day would be 15 degrees Celsius.

Which of the following is a problem of landlocked countries

Bayanin Amsa

Which of the following is a reason for the high volume of trade between Nigeria and developed countries?

Bayanin Amsa

The correct answer is "Colonial ties." One of the primary reasons for the high volume of trade between Nigeria and developed countries is the historical and economic ties that Nigeria shares with many of these nations. Nigeria was a British colony until it gained independence in 1960, and as a result, it has maintained strong trade relationships with the UK and other former British colonies. These relationships have been fostered over many years through cultural, social, and economic ties. In addition, many developed countries have invested heavily in Nigeria's natural resources, such as oil, which has further strengthened the trade relationships between Nigeria and these countries. This has led to the development of a large export market for Nigerian products, such as crude oil and natural gas. Therefore, the correct answer is "Colonial ties," as it has been a significant reason for the high volume of trade between Nigeria and developed countries.

Bayanin Amsa

A settlement located where two rivers meet is called a confluence town. A confluence is a point where two or more rivers meet and flow together as one. Settlements located at confluences are called confluence towns because they are situated at a unique and strategic location where two rivers meet. Confluence towns have historically been important for transportation, trade, and agriculture, as well as for strategic and military reasons. They are often located at the intersection of major river systems, making them important hubs for transportation and commerce. The availability of water from two rivers can also make confluence towns ideal locations for farming and irrigation. Therefore, a settlement located where two rivers meet is called a confluence town.
