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.

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.

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.

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.

The answer is "atmosphere". The atmosphere is the layer of gases that surrounds the Earth. It is made up of a mixture of gases, including nitrogen, oxygen, argon, carbon dioxide, and small amounts of other gases. The atmosphere protects the Earth from the harmful radiation from the sun and helps to regulate the temperature of the planet. It is divided into several layers, including the troposphere (where weather occurs) and the stratosphere (where the ozone layer is located). The atmosphere is essential for life on Earth, as it provides the air we breathe and plays a crucial role in the Earth's water cycle.

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.

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.

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 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 system of cultivation of tropical commercial crops estates is known as plantation agriculture. Plantation agriculture refers to a large-scale farming system where a single crop is grown on a large piece of land, usually in tropical countries. This type of agriculture is characterized by the use of large amounts of land, labor, and capital to cultivate crops such as rubber, sugar, coffee, cocoa, and tea. These crops are grown for commercial purposes, and the aim is to produce large quantities of a single product for export. The crops are typically grown in monoculture, which means that only one type of crop is grown in a particular area. This type of agriculture is often associated with the exploitation of workers, environmental degradation, and social and economic inequality.

The answer is Abuja. Dodoma is the capital city of Tanzania, and similarly, Abuja is the capital city of Nigeria. Prior to Abuja, Lagos was the capital city of Nigeria. However, due to its rapidly growing population and other challenges, the government decided to move the capital to a more central location in the country, which is Abuja. Therefore, just as Dodoma serves as the political hub of Tanzania, Abuja serves as the political center of Nigeria.

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.

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

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.

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.
