The Farthest planet from the sun in the solar system is_______

Maelezo ya Majibu

The farthest planet from the Sun in the solar system is Pluto. Pluto used to be considered the ninth planet in the solar system, but it was reclassified as a "dwarf planet" in 2006. Pluto's distance from the Sun varies because it has an elliptical orbit, which means that its distance from the Sun changes throughout its orbit. On average, Pluto is about 3.7 billion miles (5.9 billion kilometers) away from the Sun. This makes it much farther from the Sun than any of the eight "traditional" planets in the solar system, including Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. So, to summarize, Pluto is the farthest planet from the Sun in our solar system, even though it's now classified as a dwarf planet.

If the time in New York (75°W) is 5.00pm, The time in Nigeria(15°E) will be

Maelezo ya Majibu

New York (75°W) is 5 hours behind Coordinated Universal Time (UTC-5) and Nigeria (15°E) is 1 hour ahead of Coordinated Universal Time (UTC+1). Therefore, there is a time difference of 6 hours between New York and Nigeria. When it is 5.00pm in New York, we can add 6 hours to find the time in Nigeria: 5.00pm in New York + 6 hours = 11.00pm in Nigeria So the correct answer is 11.00pm.

Lines joining places with same mean annual rainfall are called___________

Maelezo ya Majibu

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.

A form of chemical weathering is__________

Maelezo ya Majibu

The form of chemical weathering is carbonation. Carbonation is a type of chemical weathering that occurs when carbon dioxide from the air reacts with minerals in rocks to form new compounds. This reaction causes the minerals in the rock to dissolve and the rock to become weaker and eventually break down into smaller pieces. This process is important in the formation of soil, as it helps break down rocks and minerals into smaller particles that can be easily transported and mixed into the soil.

Lines joining places of equal sunshine duration on maps are__________

Maelezo ya Majibu

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.

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

Maelezo ya Majibu

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.

Maelezo ya Majibu

The dominant foreign exchange earner of Senegal is groundnut. Groundnut, also known as peanut, is one of the main agricultural crops grown in Senegal. It is a versatile crop that can be used for food, oil, and animal feed. Groundnuts are an important source of income for many farmers in Senegal, and the country is one of the largest producers of groundnuts in Africa. The export of groundnuts is a significant source of foreign exchange for Senegal. The country exports groundnuts to various international markets, including Europe, Asia, and the Middle East. In addition to groundnuts, Senegal also exports other agricultural products such as fish, fruits, and vegetables, as well as textiles and chemicals. However, groundnuts remain the main foreign exchange earner for the country.

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

Maelezo ya Majibu

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.

How were the major mountain belts of the world produced?

Maelezo ya Majibu

The major mountain belts of the world were produced by a geological process known as "folding". Over millions of years, immense pressure from tectonic plates caused rocks in the Earth's crust to buckle and fold, resulting in the formation of mountain ranges. This process is often associated with the collision of two tectonic plates, which can create enormous forces that push and compress rocks together, causing them to fold and uplift into mountains. Unlike weathering or wind erosion, which wear down and erode mountains over time, folding is a constructive process that builds mountains up. While rivers and other natural forces can contribute to the formation of mountains, they are generally not the primary cause of major mountain belts. Instead, the formation of mountain ranges is primarily driven by the slow but powerful movements of the Earth's tectonic plates over long periods of time.

Maelezo ya Majibu

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

Maelezo ya Majibu

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.

When the moon comes in between the earth and the sun________

Maelezo ya Majibu

A solar eclipse occurs when the moon comes between the earth and the sun. During a solar eclipse, the moon blocks the sun's light and casts a shadow on the earth. This causes a temporary darkness in the middle of the day and is a spectacular sight to see. Solar eclipses can only happen during a full moon and are relatively rare events. They occur because the moon and the sun are exactly in line with the earth and the moon's shadow falls on the earth.

The peeling off of surface layers of a rounded boulders during mechanical weathering is called________

Maelezo ya Majibu

The peeling off of surface layers of a rounded boulder during mechanical weathering is called exfoliation. Exfoliation is a type of mechanical weathering process that occurs when layers of rock or boulder peel off from the surface due to pressure release. The process usually occurs in rocks that have been exposed to intense heat, pressure, and other environmental factors for a long time. As a result of these factors, the rock expands and contracts repeatedly, causing the surface layers to crack and break apart. Over time, these cracks become wider, and the layers begin to peel off, revealing the smooth and rounded boulder underneath. Exfoliation is often seen in granitic rocks, where the outer layers peel off to form concentric layers resembling an onion. The process can also occur in other rock types such as sandstone and shale. Overall, exfoliation is an important geological process that contributes to the breakdown and erosion of rocks over time, shaping the landscape around us.

The difference between high tide and low tide is referred to as__________

Maelezo ya Majibu

The difference between high tide and low tide is referred to as "tidal range". Tidal range is the vertical distance between the highest water level of a high tide and the lowest water level of a low tide. In other words, it is the difference in height between the highest and lowest water levels during a tidal cycle. Tidal range can vary depending on the location, the phase of the moon, and other factors such as weather conditions. It is an important measurement for activities such as boating, fishing, and coastal engineering, as well as for understanding and predicting the effects of sea level changes on coastlines.

All the following are environmental hazards except___________

Maelezo ya Majibu

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.

The basic mineral that is common to Sokoto, Ewekoro, Calabar, and Nkalagu is limestone. Limestone is a sedimentary rock that is composed mainly of calcium carbonate, which is a mineral that is commonly found in the Earth's crust. It is a very versatile mineral that has a wide range of applications, including in the construction industry, as a raw material for cement production, and in agriculture as a soil conditioner. Sokoto, Ewekoro, Calabar, and Nkalagu are all regions in Nigeria that have abundant deposits of limestone. The limestone in these areas is of high quality and is a significant source of revenue for the local economy. It is usually mined from quarries and then processed into various forms for its different uses. Therefore, the basic mineral that is common to all these areas is limestone, which is an essential raw material for various industries and is vital for economic growth and development.

Organic components of the soil include all the following except_______

Maelezo ya Majibu

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.

Maelezo ya Majibu

Lake Kivu and Lake Malawi are related in that they are both rift valley lakes. A rift valley lake is a type of lake that forms in a depression or basin created by tectonic activity. In the case of these two lakes, they were formed as a result of the East African Rift, which is a large geological rift that stretches for thousands of kilometers through Eastern Africa. The two lakes are located in different parts of the rift, with Lake Kivu in the western branch and Lake Malawi in the southern branch, but they share a common geological origin.

Latitude 66 and half marks the____________

Maelezo ya Majibu

Latitude 66 and a half (66.5) marks the Arctic Circle. The Arctic Circle is an imaginary line that circles the Earth at approximately 66.5 degrees latitude, which is located in the northern hemisphere. This line marks the southernmost point at which the sun can remain continuously above or below the horizon for a full 24 hours, depending on the time of year. Therefore, if you are at a location with latitude 66.5 degrees or higher, it means that you are within the Arctic Circle and can experience the phenomenon of the midnight sun during the summer solstice, where the sun remains above the horizon for a full 24 hours. In contrast, during the winter solstice, the sun will not rise above the horizon at all, resulting in 24 hours of darkness. Hence, the correct answer is: - Arctic Circle

One of the following does not determine the availability of resources in a country____________

Maelezo ya Majibu

Evolution does not determine the availability of resources in a country. Evolution refers to the gradual changes in species over time through the process of natural selection. It has no direct effect on the availability of resources in a country. Population, emigration, and morbidity, on the other hand, can influence the availability of resources in a country. A large population can lead to increased demand for resources, while emigration can decrease the number of people using those resources. Morbidity, or the rate of illness and disease in a population, can also impact the availability of resources, as a large portion of the population may require medical attention and resources.

The innermost section of the Earth is the__________

Maelezo ya Majibu

The innermost section of the Earth is the core. The Earth's core is the central part of our planet, located beneath the mantle. It is composed primarily of iron and nickel, and is divided into two distinct layers: the outer core and the inner core. The outer core is a liquid layer that surrounds the solid inner core. The inner core is a solid, dense ball of metal that is about the size of the Moon. The core plays a crucial role in the Earth's magnetic field, which helps protect our planet from harmful solar radiation. The core also generates the heat that drives the movement of the Earth's tectonic plates, which causes earthquakes and volcanic eruptions. Understanding the properties and behavior of the Earth's core is an important area of research in the field of geophysics.

The amount of precipitation throughout the year is moderate, with the wettest month being July with 71mm of rainfall.

A river transport its load through the following processes except_________

Maelezo ya Majibu

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.
