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.

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

Maelezo ya Majibu

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.

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.

All the following are environmental hazards except___________

Maelezo ya Majibu

The environmental hazard among the given options that is not included is afforestation. Afforestation refers to the process of planting trees in an area where there was no forest, or the forest has been destroyed, and it is typically seen as a positive action for the environment. On the other hand, the other three options are environmental hazards that can have negative impacts on people and the environment. Flooding, for example, can lead to property damage, displacement of people, and loss of life. Vulcanicity, which refers to the movement of magma and volcanic activity, can result in the release of toxic gases, destruction of property, and loss of life. Deforestation, which is the clearing of forests for various human activities, can cause soil erosion, loss of biodiversity, and contribute to climate change.

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.

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

Maelezo ya Majibu

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.

The greatest volcanic regions of Africa are found in

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.

Lines joining places with same mean annual rainfall are called___________

Maelezo ya Majibu

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 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 basic mineral that is common to Sokoto, Ewekoro, Calabar, and Nkalagu is limestone. 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.

The Farthest planet from the sun in the solar system is_______

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.

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

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.

The innermost section of the Earth is the__________

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

A line joining places having an equal degree of cloudiness is called an "isoneph". An "isoneph" is a line on a weather map that connects points of equal cloud cover. It helps meteorologists to understand the distribution of clouds in a particular area and to forecast weather patterns. By analyzing the movement of isonephes, they can predict changes in cloud cover and the potential for precipitation.

Study the map and answer the question. The bearing of Jata from Adaba is approximately

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.

The earth is enveloped by a mixture of gases referred to as the___________

Maelezo ya Majibu

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.

The feature is one or the land forms associated with_________

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.

Maelezo ya Majibu

The annual temperature range at station Q is calculated as the difference between the highest and the lowest temperature recorded in a year. The highest temperature recorded at the station in the given table is 19°C and the lowest temperature recorded is -11°C. Hence, the annual temperature range at the station Q is 19°C - (-11°C) = 30°C. So, the answer is 30°C.

A desert country which has a high population density supported by irrigation is___________

Maelezo ya Majibu

Egypt is a desert country which has a high population density supported by irrigation. Irrigation is the process of supplying water to crops and lands to help them grow. In Egypt, the Nile River provides water for irrigation, allowing agriculture to flourish and supporting the country's large population. This is why Egypt is considered a good example of a desert country with a high population density that is supported by irrigation.
