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 oldest system of agriculture in Nigeria which now survives only in very remote areas is
Maelezo ya Majibu
The oldest system of agriculture in Nigeria which now survives only in very remote areas is shifting cultivation, also known as slash-and-burn agriculture. Shifting cultivation involves cutting down a patch of forest or woodland, burning the vegetation, and planting crops in the ash-enriched soil. Farmers would use the land for a few years until the soil fertility decreases, then abandon it and move to a new area, leaving the old area to regenerate into forest or woodland. This practice was sustainable when population densities were low and farmers had access to vast areas of land. However, with the growth of population and increased pressure on land, shifting cultivation has become less sustainable, leading to soil degradation, deforestation, and loss of biodiversity. Today, shifting cultivation survives only in very remote areas, where population densities are still low and access to land is not restricted.

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.

Which of the following countries has the least potential for the production of steel?
Maelezo ya Majibu
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.

Which of the following is not a form of mass movement?
Maelezo ya Majibu
The answer is "earthquake" as it is not a form of mass movement. Mass movement refers to the process by which large amounts of soil, rock, and other debris move down a slope under the influence of gravity. Landslides, rockslides, and talus creep are all examples of mass movement. An earthquake, on the other hand, is a sudden shaking of the earth's surface caused by the movement of tectonic plates. While earthquakes can cause landslides and other types of mass movement, the earthquake itself is not a form of mass movement. Instead, it is a geological event that can trigger mass movement in the surrounding area.

Maelezo ya Majibu
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.

If the distance between two places on a map is 2cm, while the distance on land is 4km, the scale of the map is
Maelezo ya Majibu
The scale of a map is the ratio of the distance on the map to the actual distance on land. It is usually written as a fraction, like 1:100,000, where the first number represents the distance on the map and the second number represents the corresponding distance on land. To find the scale of the map in question, we need to divide the actual distance on land (4km) by the distance on the map (2cm). First, we need to convert 4 km to cm: 4 km = 4 x 10^3 m = 4 x 10^3 x 100 cm = 4 x 10^5 cm Now, we divide the actual distance on land (4 x 10^5 cm) by the distance on the map (2 cm): (4 x 10^5 cm) / (2 cm) = 2 x 10^5 So the scale of the map is 1 : 2 x 10^5, which is equivalent to 1:200,000.

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
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.

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.

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.

Maelezo ya Majibu
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.

Maelezo ya Majibu
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.
