Organic components of the soil include all the following except_______

Awọn alaye Idahun

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.

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

Awọn alaye Idahun

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.

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.

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

Awọn alaye Idahun

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.

Latitude 66 and half marks the____________

Awọn alaye Idahun

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

Awọn alaye Idahun

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.

The innermost section of the Earth is the__________

Awọn alaye Idahun

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.

A mercury barometer is used for measuring_________

Awọn alaye Idahun

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.

Awọn alaye Idahun

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.

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

Awọn alaye Idahun

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.

The greatest volcanic regions of Africa are found in

Awọn alaye Idahun

The greatest volcanic regions of Africa are found in two main areas: Kenya and Tanzania, and Sudan and Ethiopia. In Kenya and Tanzania, the Great Rift Valley runs through the region and is home to some of the most iconic volcanic features on the continent. The valley is characterized by a series of interconnected volcanoes, hot springs, geysers, and lakes. The most famous volcanic peaks in the area are Mount Kilimanjaro, Mount Kenya, and Mount Meru. In Sudan and Ethiopia, the East African Rift Valley also runs through the region and is another hotspot for volcanic activity. The valley is home to a number of active and dormant volcanoes, including Erta Ale, Nyiragongo, and Mount Karthala. In addition, the region is known for its geothermal activity, with numerous hot springs and geysers dotting the landscape. Both of these regions are characterized by their tectonic activity, with the movement of the Earth's crust leading to the formation of rift valleys, which in turn create the conditions for volcanic activity. The result is a stunning and unique landscape that draws visitors from all over the world.

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

Awọn alaye Idahun

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.

Awọn alaye Idahun

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.

Awọn alaye Idahun

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.

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

Awọn alaye Idahun

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.

When the moon comes in between the earth and the sun________

Awọn alaye Idahun

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.

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

Awọn alaye Idahun

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.

Awọn alaye Idahun

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.

The feature is one or the land forms associated with_________

Awọn alaye Idahun

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.

How were the major mountain belts of the world produced?

Awọn alaye Idahun

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.
