Maelezo ya Majibu
A non-renewable resource is a resource that cannot be easily replenished or regenerated. An example of a non-renewable resource is mineral, such as coal, oil, and natural gas. These resources are formed over millions of years and are finite, meaning they will eventually run out. Unlike renewable resources, like wind and solar power, which can be replenished, non-renewable resources are being consumed faster than they can be replaced. This is why it's important to use these resources wisely and find alternative energy sources to preserve them for future generations.

Maelezo ya Majibu
The Stevenson's screen is a box used to house weather instruments that measure temperature, humidity, and other meteorological variables. It is raised about one meter above the ground to avoid the heat from the ground. When the screen is placed on the ground, it can absorb and radiate heat from the ground, which can affect the accuracy of temperature measurements. By raising it one meter above the ground, the screen is more exposed to the free atmosphere and less affected by the heat from the ground. Additionally, raising the screen helps to reduce the impact of raindrops entering the instruments during heavy rainfall. The height also helps to avoid the effects of nearby trees and other obstacles that could affect wind flow around the instruments and affect the measurements. Therefore, the main reason for raising the Stevenson's screen one meter above the ground is to ensure that the weather instruments inside are measuring the temperature and other meteorological variables accurately and without interference from external factors.

Maelezo ya Majibu
The rock that is formed by wood subjected to pressure and heat is called "lignite". Lignite is a type of coal that is considered the lowest rank of coal due to its relatively low heat content and carbon content. Lignite is formed from partially decomposed plant material that has been subjected to increasing amounts of pressure and heat over time. As the plant material becomes buried and compressed, it eventually transforms into lignite through a process called coalification. Therefore, lignite is a sedimentary rock that is formed from the compressed and heated remains of plants, including wood. It is typically brownish-black in color and has a relatively low density compared to other types of coal.

What is the birth rate of a country with a total population of 150,000,000 and registered births of 3,000,000 in a given year?
Maelezo ya Majibu
To calculate the birth rate of a country, we need to divide the number of registered births by the total population of the country and then multiply by 100 to get a percentage. In this case, the number of registered births is 3,000,000, and the total population of the country is 150,000,000. So the birth rate is (3,000,000 / 150,000,000) x 100, which simplifies to 2%. Therefore, the answer is%, meaning that the birth rate of the given country is 2%.

Maelezo ya Majibu
The desert country with high population density supported by irrigation is Egypt. Egypt is located in the northeastern part of Africa and is mostly covered by the Sahara desert. Despite the desert conditions, Egypt has a high population density due to the Nile river that runs through the country. The Nile river provides water for irrigation, which has allowed for the cultivation of crops and supported the growth of a population in what would otherwise be an uninhabitable region. The ancient Egyptians were able to take advantage of the Nile's seasonal floods and develop a complex system of canals and irrigation to grow crops. Today, modern irrigation techniques have allowed Egypt to continue to support a high population density and grow crops such as wheat, cotton, and fruits.

The best technique to prevent soil erosion in a humid, gently sloping area is to adopt
Maelezo ya Majibu
The best technique to prevent soil erosion in a humid, gently sloping area is contour ridging. Contour ridging involves creating ridges that run along the contour lines of the slope, which helps to slow down the flow of water across the surface of the soil. This technique helps to trap water, reduce its speed, and allow it to penetrate into the soil. By reducing the speed of water, contour ridging also helps to reduce the amount of soil that is carried away by the water, which reduces erosion. Terrace cultivation and intercropping can also be effective techniques for reducing erosion, but they are generally better suited to steeper slopes. Wind breakers can help to reduce erosion caused by wind, but they are not as effective for preventing erosion caused by water. In summary, contour ridging is the best technique for preventing soil erosion in a humid, gently sloping area because it helps to slow down the flow of water and reduce erosion, and it is well-suited to this type of terrain.

If the standard time of a country is GMT + 1hr, which longitude's local time is adopted by the country?
Maelezo ya Majibu
The standard time of a country is determined by the longitude of its location on the Earth. A time zone is a region that has the same standard time, and time zones are typically defined as an offset from the Coordinated Universal Time (UTC). In this case, the country has a standard time of GMT + 1 hour, which means it is one hour ahead of the UTC. The longitude that corresponds to this time zone is the one located 15° east of the Prime Meridian, which runs from the North Pole to the South Pole and passes through the Royal Observatory in Greenwich, London, England. So, the local time adopted by the country is 15°E.

Maelezo ya Majibu
The development of climax vegetation in the savannah belt of Nigeria is mainly disturbed by bush burning. This is because frequent burning of the grassland destroys the vegetation cover, which can prevent the establishment of trees and other woody plants that are characteristic of climax vegetation. Bush burning also leads to a reduction in soil nutrients, making it difficult for plants to grow. Although activities such as lumbering, mining, and animal grazing can also contribute to the disturbance of climax vegetation, they are not the main cause. Lumbering and mining, for example, involve the removal of trees and vegetation, but these activities are typically limited in scale and do not occur as frequently as bush burning. Animal grazing can also have an impact on vegetation, but it is usually managed in a way that allows for the recovery of the grassland. Therefore, it is the frequent and uncontrolled practice of bush burning that is the primary cause of disturbance to the development of climax vegetation in the savannah belt of Nigeria.

Which of the following is most influential in the location of textile and footwear industries?
Maelezo ya Majibu
Among the options given, the most influential factor in the location of textile and footwear industries is abundant cheap labor. Textile and footwear industries require a large labor force to produce goods at a low cost. If a country has a large supply of labor willing to work for low wages, it can attract textile and footwear industries to set up factories in its territory. This is because labor is usually the largest cost for these industries, and a country with cheap labor can offer cost advantages to manufacturers. Raw materials are also important for these industries, but they can be imported from other countries if they are not available locally. Energy supply and low interest rates may also affect the cost of production, but they are less critical factors than the availability of cheap labor. In summary, countries with a large supply of cheap labor have an advantage in attracting textile and footwear industries because they can offer low production costs to manufacturers, making their products more competitive in the global market.

Maelezo ya Majibu
The best way to prevent a watershed from degradation is through forest reservation. Watersheds are areas of land that drain into a common body of water, such as a river or a lake. Forest reservation refers to the process of setting aside and protecting areas of forest from human activities that may cause harm to the ecosystem. Forests are important in watersheds because they help regulate water flow, filter pollutants, and provide habitat for wildlife. Fuel wood extraction and crop production can cause harm to watersheds if they are not managed sustainably. Fuel wood extraction can lead to deforestation, soil erosion, and loss of biodiversity, which can in turn impact water quality and quantity. Crop production can lead to the use of fertilizers and pesticides that can runoff into the water, causing pollution. Inter-basin transfer is the process of diverting water from one basin to another. While it can be a solution to water scarcity, it can also have negative impacts on watersheds, including altering natural water flow, disrupting ecosystems, and reducing water availability downstream. In summary, forest reservation is the best way to prevent watershed degradation as it helps to maintain the natural ecosystem functions that are important for water quality and quantity.
