Lines joining places of equal sunshine duration on maps are__________

Isohel

Isoneph

Isohyet

Isohert

Answer Details

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.

Question 6 Report

In which of the following rock types is petroleum mainly found?

Metamorphic

Plutonic

Igneous

Volcanic

Sedimentary

Answer Details

Petroleum is mainly found in sedimentary rocks. Sedimentary rocks are formed from the accumulation and cementation of sediments, which can include organic matter such as dead plants and animals. Over time, this organic matter can become buried and subjected to heat and pressure, which can transform it into petroleum through a process called diagenesis. Petroleum is a fossil fuel that is composed of hydrocarbons, which are molecules made up of carbon and hydrogen atoms. The organic matter in sedimentary rocks that forms petroleum is usually derived from marine plants and animals that died and sank to the bottom of the ocean. Over time, these organic remains can be buried by layers of sediment, and the heat and pressure from the overlying rocks can cause them to be transformed into petroleum. While it is possible for petroleum to be found in other types of rocks, such as metamorphic rocks that have undergone extreme heat and pressure, sedimentary rocks are by far the most common type of rock that contains petroleum. This is because the process of petroleum formation requires the accumulation and burial of organic matter, which is most likely to occur in sedimentary environments such as oceans, lakes, and swamps.

When the moon comes in between the earth and the sun________

eclipse of the moon occurs

a solar eclipse occurs

the length of the day varies

the length of the day increases

Answer Details

A solar eclipse occurs when the moon comes between the earth and the sun. During a solar eclipse, the moon blocks the sun's light and casts a shadow on the earth. This causes a temporary darkness in the middle of the day and is a spectacular sight to see. Solar eclipses can only happen during a full moon and are relatively rare events. They occur because the moon and the sun are exactly in line with the earth and the moon's shadow falls on the earth.

Question 13 Report

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

Evolution

Emigration

Population

Morbidity

Answer Details

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 peeling off of surface layers of a rounded boulders during mechanical weathering is called________

Rock fragmentation

Solifluction

Exfoliation

Weathering

Answer Details

The peeling off of surface layers of a rounded boulder during mechanical weathering is called exfoliation. Exfoliation is a type of mechanical weathering process that occurs when layers of rock or boulder peel off from the surface due to pressure release. The process usually occurs in rocks that have been exposed to intense heat, pressure, and other environmental factors for a long time. As a result of these factors, the rock expands and contracts repeatedly, causing the surface layers to crack and break apart. Over time, these cracks become wider, and the layers begin to peel off, revealing the smooth and rounded boulder underneath. Exfoliation is often seen in granitic rocks, where the outer layers peel off to form concentric layers resembling an onion. The process can also occur in other rock types such as sandstone and shale. Overall, exfoliation is an important geological process that contributes to the breakdown and erosion of rocks over time, shaping the landscape around us.

The plains formed when the slopes of mountains are worn back in arid and semi-arid regions my mechanical weathering is called_______

Alluvial plains

Outwash plains

Pediplains

Savanna plains

Answer Details

The plains formed when the slopes of mountains are worn back in arid and semi-arid regions by mechanical weathering is called "Pediplains". Pediplains are a type of plain that form as a result of the gradual erosion and weathering of mountains and hills. They typically occur in arid and semi-arid regions where there is little vegetation to protect the land from erosion. Over time, as the wind, rain, and other natural forces wear away at the mountain slopes, sediment is carried downhill and deposited on the surrounding plain. This sediment can be made up of rocks, sand, and soil, and can create a relatively flat and gently sloping plain that extends out from the base of the mountain. Unlike other types of plains, such as alluvial plains or outwash plains, which are formed by water deposition, pediplains are formed by the mechanical weathering and erosion of rock and soil. They are typically found in regions where there is little precipitation and where the climate is dry and hot, which can help to speed up the weathering process.

Answer Details

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

If the distance between two places on a map is 2cm, while the distance on land is 4km, the scale of the map is

1:100,000

1:200,000

1:50,000

1:150,000

Answer Details

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.

more females than males

Answer Details

A broad-based population pyramid is composed mainly of young dependants and active inhabitants. This means that there are more people in the younger age brackets (typically 0-14 years old) and a significant proportion of the population is in the working age bracket (typically 15-64 years old). The number of elderly people (typically 65 years and above) in this type of pyramid is relatively small. Broad-based population pyramids are typically associated with countries that have high birth rates and lower life expectancies. In these countries, the younger population tends to be larger and the older population tends to be smaller due to factors such as high infant mortality rates and shorter life spans. The larger working-age population in these countries can be a potential source of economic growth if they are able to find employment and contribute to the country's development.
