Which of the following is an effect of the earth's revolution?
Maelezo ya Majibu
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.

The correct arrangement of the layers of the earth crust from the surface to the interior is
Maelezo ya Majibu
The correct arrangement of the layers of the earth's crust from the surface to the interior is "sial, sima, mantle, and core." The outermost layer of the earth is called the crust, which is divided into two types: the continental crust and the oceanic crust. The continental crust is made up of a type of rock called "sial," which stands for "silicon" and "aluminum." This layer is relatively thicker and less dense than the oceanic crust. The oceanic crust, on the other hand, is made up of a type of rock called "sima," which stands for "silicon" and "magnesium." This layer is relatively thinner and denser than the continental crust. Beneath the crust is the mantle, which is made up of solid, dense rock. The mantle is the thickest layer of the earth and is responsible for convection currents that drive plate tectonics. The temperature and pressure in the mantle increase with depth. Finally, the core of the earth is located at the center of the planet and is made up of two parts: the outer core and the inner core. The outer core is made up of liquid iron and nickel, while the inner core is made up of solid iron and nickel. The core is the hottest and densest part of the planet, and it is responsible for generating the earth's magnetic field. In summary, the correct arrangement of the layers of the earth's crust from the surface to the interior is sial, sima, mantle, and core.

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
Maelezo ya Majibu
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.

Which of the following farming activity best describes the rearing of only animals like cattle, sheep and goat mainly in the savanna belt of the north?
Maelezo ya Majibu
Pastoral farming best describes the rearing of only animals like cattle, sheep, and goat mainly in the savanna belt of the north. Pastoral farming is a type of agricultural activity that involves the rearing of domesticated animals, such as cattle, sheep, and goats, in an extensive system, where the animals are allowed to roam freely over large areas of land. Pastoral farming is often practiced in regions with large areas of grassland, such as the savanna belt in the north of Nigeria, where the animals are able to find enough food and water to sustain themselves. Intensive farming, on the other hand, is a type of agricultural activity that involves the intensive use of inputs, such as land, labor, and capital, to maximize production. Intensive farming is often practiced in regions with high population densities and limited land resources. Animal farming is a general term that can refer to any type of farming that involves the rearing of animals, including both pastoral and intensive farming. Mixed farming is a type of agricultural activity that involves the simultaneous production of crops and livestock, often on the same piece of land.

Maelezo ya Majibu
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."

Maelezo ya Majibu
The best solution to the rapid depletion of forest resources in West Africa is to introduce forest conservation techniques. This approach involves implementing sustainable practices that protect the natural environment and enable communities to benefit from the forest resources without damaging them. It includes measures such as reducing deforestation, promoting reforestation, and enforcing laws against illegal logging and other harmful activities. Reserving hectares of land for plantations may not be a sustainable solution, as it can lead to monoculture and may not provide the same benefits as natural forests. Importing wood from other countries may exacerbate the problem, as it encourages overconsumption and does not address the underlying issues of deforestation. Employing more forest guards can help deter illegal activities, but it may not be enough without also implementing conservation techniques. Therefore, implementing forest conservation techniques is the best solution as it promotes the sustainable use of forest resources while protecting the natural environment and supporting local communities.

Maelezo ya Majibu
A line joining all points of equal salinity is an isohaline. In simpler terms, salinity refers to the amount of salt in water, and an isohaline is a line on a map that connects all the points in a body of water that have the same level of salinity. So, if you were to take a water sample at each point along an isohaline, you would find that they all have the same amount of salt in them. Isohalines are important in oceanography and marine biology because changes in salinity can affect the behavior and distribution of marine organisms, as well as ocean currents and other physical processes.

Maelezo ya Majibu
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.

Maelezo ya Majibu
In the desert region, the most prominent agent of erosion is wind. The wind in the desert can pick up sand and other loose materials and carry them across the landscape, which can cause erosion over time. As the wind blows across the desert, it can pick up loose sand and other sediments and transport them from one location to another. This process, known as "deflation," can cause the erosion of the desert surface over time. In addition, the wind can also cause abrasion, which occurs when sand particles are carried by the wind and collide with other surfaces, such as rocks or other sediments. This can wear away the surface of the rocks or other materials over time, leading to erosion. Overall, wind erosion is a very important process in the desert environment and plays a significant role in shaping the landscape over time.

If the scale of a map is 2cm to 1km, what is the ground distance if the distance between two towns on the map is 20cm
Maelezo ya Majibu
If the scale of a map is 2cm to 1km, it means that for every 2 centimeters on the map, there is a real-world distance of 1 kilometer. To find the ground distance between two towns on the map, we need to convert the distance on the map into a real-world distance. If the distance between the two towns on the map is 20cm, we can start by calculating how many kilometers it represents in the real world. Since the scale is 2cm to 1km, we can divide the distance on the map by 2 to get the real-world distance: 20 cm / 2 = 10 km Therefore, the ground distance between the two towns is 10 kilometers. So the answer is: 10km.

Cement factory is usually located near
Maelezo ya Majibu
Cement factories are usually located near sources of raw materials. Raw materials such as limestone, clay, shale, and other minerals are used to produce cement. These materials are usually found in abundance in certain geological formations or deposits. Transporting these raw materials over long distances can be costly and time-consuming, so it makes sense for cement factories to be located as close as possible to the sources of these materials. This helps to keep production costs low and ensures a steady supply of raw materials for the factory. Additionally, being close to the raw materials can also help to reduce the environmental impact of the factory. If the raw materials have to be transported over long distances, this can lead to increased emissions from transportation vehicles, which can contribute to air pollution and climate change. Therefore, to ensure the efficient and sustainable production of cement, it is common for cement factories to be located near sources of raw materials.

Which of the following rocks is organically formed?
Maelezo ya Majibu
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.
