Question 2 Report

Markets is the rural areas play an important role in the domestic production process because they?

enable people buy their needs

make it necessary to build rural roads

bring people together from far and near

serve as collecting and distributing centers for rural products

Answer Details

Markets in rural areas play an important role in the domestic production process because they serve as collecting and distributing centers for rural products. Rural areas are typically agricultural regions where farmers produce various crops and livestock. However, these farmers often face the challenge of finding buyers for their products. This is where rural markets come in. Rural markets provide a central location where farmers can bring their produce to sell and buyers can come to purchase goods. By serving as collecting and distributing centers, rural markets help to connect farmers with consumers and facilitate the exchange of goods. This promotes domestic production and supports the local economy. Furthermore, rural markets also serve as social centers, bringing people together from far and near. This creates opportunities for people to exchange ideas and information, and helps to build a sense of community in rural areas. While rural markets do enable people to buy their needs, and may make it necessary to build rural roads for transportation, their primary role in the domestic production process is as collecting and distributing centers for rural products.

Question 6 Report

A river loses energy and may deposit some of its load if?

its bed and banks become smoother

its discharge increases

its gradient decreases

it becomes narrow and deep

Answer Details

A river loses energy and may deposit some of its load if its gradient decreases. Gradient refers to the slope of the riverbed, and a decrease in gradient means the river is becoming less steep. As the river becomes less steep, it loses energy and cannot carry its load (the sediment and debris it is transporting) as efficiently. This can result in the deposition of some of the load, leading to the formation of features such as bars and islands.

Question 7 Report

Vegetation regeneration on a fallow land is typical example of?

nature conservation

secondary succession

reafforestation

forest reservation

Answer Details

Fallow land refers to an agricultural field that has been left uncultivated for a period of time. When such land is left fallow, it allows natural vegetation to regenerate on the land without human intervention. This process is an example of secondary succession, which is the natural process of ecological change that occurs after a disturbance, such as fire, flood or in this case, abandonment of an agricultural field. The other options - nature conservation, reafforestation and forest reservation - generally refer to deliberate human efforts to manage and preserve forests and natural habitats.

Question 8 Report

Chemical weathering is both rapid and intense in the humid tropics because of?

low annual range of temperature

high rainfall and temperature

the presence of easily weathered rocks

a large volumes of run-off

Answer Details

Chemical weathering is both rapid and intense in the humid tropics because of high rainfall and temperature. Chemical weathering is the breakdown of rocks through chemical processes such as dissolution, oxidation, and hydrolysis. In the humid tropics, the combination of high rainfall and temperature increases the rate of chemical weathering because water and heat are key components in many chemical reactions that break down rocks. The high rainfall increases the availability of water for chemical reactions, while the high temperature speeds up the reactions. As a result, chemical weathering in the humid tropics is more rapid and intense than in other regions with lower rainfall and temperature. The presence of easily weathered rocks and large volumes of run-off can also contribute to chemical weathering in the humid tropics, but they are not the main factors.

Question 9 Report

A common problem of the land-locked states of Africa is that?

they have the least developed internal transport network

they are the poorest countries of Africa

imported goods cost twice their normal prices

they are dependent on the coastal neighbours for access to the sea

Answer Details

Land-locked states of Africa are countries that do not have direct access to the sea. One common problem they face is that they are dependent on their coastal neighbors for access to seaports and international trade routes. This often leads to higher transportation costs for imported goods, which can affect their economies negatively. Additionally, these countries may also have limited access to resources, which can further hinder their development. Therefore, the correct option is "they are dependent on the coastal neighbors for access to the sea".

Question 11 Report

Why are the major Africa rivers of limited value for transportation?

The river courses are too narrow for vessels

Rail transport is cheaper than water transport

The rivers flow through sparsely populated areas

The rivers channels interrupted by rapids, falls and sandbars

Answer Details

The major rivers in Africa are of limited value for transportation because their channels are often interrupted by rapids, falls, and sandbars. These natural obstacles make it difficult for boats and ships to navigate through the rivers. Additionally, many of the rivers flow through areas with a low population density, which means that there is not enough demand for transportation along these routes. Finally, rail transport is often cheaper and more efficient than water transport, which further limits the use of rivers for transportation.

The waters off the east coast of Canada are rich in fish because?

of the abundance of plankton

they are pollution-free

they are deep and warm

they are rarely distributed by ocean-going vessels

Answer Details

The waters off the east coast of Canada are rich in fish because of the abundance of plankton. Plankton are tiny organisms that live in water and are an important food source for many fish species. The waters in this region are nutrient-rich, which supports the growth of plankton, which in turn attracts fish to the area. The nutrient-rich waters are caused by a combination of factors such as ocean currents, upwelling, and freshwater runoff from the land. Additionally, the region is relatively pollution-free, which helps to maintain a healthy ecosystem.

maturity

Answer Details

Time, as a factor of soil formation, mainly influences soil maturity. Over time, the other factors of soil formation such as climate, organisms, relief, and parent material work together to weather and break down rocks, forming new soil. As time goes by, the soil becomes more mature, which means it has reached a state of stability, with a balance of physical, chemical, and biological properties. The maturity of the soil affects its productivity, water-holding capacity, and nutrient content. Therefore, time is an important factor in determining the quality of soil for agricultural purposes.

Answer Details

Pastoral nomadism, which involves the seasonal movement of herds of animals from place to place in search of pasture and water, was not native to the American continents or Australia because the natural environments in these regions were not favorable for animal rearing. The native vegetation and soil conditions did not support the growth of the types of grasses and other plants that are ideal for grazing, and there were few water sources that could sustain large herds of animals. Additionally, the native populations in these regions had other means of subsistence, such as hunting and gathering, fishing, and agriculture, that were more suited to their environments.

Which of the following population characteristics is associated with developed countries?

Decline birth rate and high death rate

High birth rate and declining death rate

High birth rate and low death rate

Low birth rate and low death rate

Answer Details

Developed countries are typically associated with a low birth rate and a low death rate. This means that the number of births per year is relatively low, and the number of deaths is also low. This can be attributed to several factors, including improved access to healthcare, better nutrition, and education. These factors lead to better health outcomes and longer life expectancies, which in turn can result in a decrease in the number of births, as parents may choose to have fewer children. Additionally, developed countries typically have access to a wide range of family planning services, which can help individuals and couples to plan their families and prevent unwanted pregnancies. A low birth rate and a low death rate are often seen as indicators of a developed and prosperous society, as they suggest that the population is healthy, well-educated, and has access to good healthcare.

Which of the following farming practices may be used to check soil erosion?

Ploughing of land upslope

Contour ploughing

Bush burning

Shifting cultivation

Answer Details

Contour ploughing may be used to check soil erosion. Contour ploughing is a farming practice that involves ploughing across the slope of the land, rather than up and down the slope. By ploughing along the contour lines, the soil is held in place and water is absorbed into the soil, reducing the risk of erosion. This technique helps to maintain soil fertility and also helps to conserve water by reducing the amount of runoff.

The problems of irregular levels of water in river navigation may be solved by?

straightening river courses

controlling the currents

providing dams, canals and locks

changing the diretion of river flow

Answer Details

The problems of irregular levels of water in river navigation may be solved by providing dams, canals, and locks. Irregular levels of water in rivers can cause problems for navigation, such as making it difficult for ships to travel through shallow waters or causing hazards due to changes in water levels. One way to solve this problem is by constructing dams, canals, and locks. Dams can help regulate the water flow of a river by storing water during periods of high rainfall and releasing it during periods of low rainfall. This helps maintain a consistent water level for navigation. Canals can be built parallel to rivers, allowing boats and ships to travel along a smooth and regular path without being affected by the irregularities of the river. Locks can be installed in canals and rivers to raise and lower water levels, allowing boats and ships to navigate through different water levels. Straightening river courses and changing the direction of river flow may not be effective solutions for irregular levels of water in river navigation. Controlling currents may also not be an effective solution as currents can be unpredictable and can change quickly. Overall, providing dams, canals, and locks is an effective way to solve the problems of irregular levels of water in river navigation.

Answer Details

Coal is likely to be absent in a region consisting mainly of igneous and metamorphic rocks. This is because coal is formed from the accumulation and compression of plant material over millions of years, which typically occurs in sedimentary environments such as swamps and marshes. Igneous and metamorphic rocks, on the other hand, are formed from molten magma or existing rock that has been altered by heat and pressure, and do not typically contain the organic material necessary for coal formation. Therefore, it is unlikely for coal to be present in a region consisting mainly of igneous and metamorphic rocks.
