R: The release of toxic and non-biodegradable wastes from industries and urban sewerages, open defecation, etc. have created many health hazards.

Detailed Solution for Geography: CUET Mock Test - 10 - Question 1

The release of toxic and non-biodegradable wastes from industries and urban sewerages, open defecation, etc. have created many health hazards. The Government of India has taken many steps to address these problems and the Swachh Bharat Mission is one of these. Municipal waste, industrial effluents and pollutants generated by transport, etc., are major sources of pollution in urban India. Open defecation in rural areas and in urban slums is a major source of pollution. The Government of India with its flagship programme 'Swachh Bharat Mission (SBM)' aims at a pollution-free environment.

Geography: CUET Mock Test - 10 - Question 2

Which of the following is/are the negative consequence(s) of international trade?

a. Commercial rivalry
b. Uneven levels of development
c. Exploitation of natural resources

Detailed Solution for Geography: CUET Mock Test - 10 - Question 2

International trade can prove to be detrimental to nations. It leads to dependence on other countries, uneven levels of development, exploitation, and commercial rivalry leading to wars. Global trade affects many aspects of life; it can impact everything from the environment to health and well-being of the people around the world. As countries compete to trade more, production and the use of natural resources spiral up, and resources get used up faster than they can be replenished. International trade has resulted in creating 'dual economies' in underdeveloped countries, as a result of which the export sector became an island of development while the rest of the economy remained backward. As a result, marine life is also depleting fast, which is resulting in uneven development.

Africa, North America, and South America each has three megacities. China is the country with the most megacities (five): Shanghai, Beijing, Guangzhou, Shenzhen, and Tianjin.

Geography: CUET Mock Test - 10 - Question 6

A famous international clothing brand has set up production operations in a small town in India. It so happens that 80% of its workers are women, who are skilled tailors but paid very low wages.

What is the most likely reason for the company to set up production in this Indian town?

Detailed Solution for Geography: CUET Mock Test - 10 - Question 6

The primary reason why the brand has set up its production facilities in a specific town is to bring down the costs of production in order to increase profits. Only option C explains this. Options B and D are incorrect as if these were the intentions of the brand, then the wages paid would be higher. Higher wages would ensure women empowerment and development of the town because of higher wages being paid to its residents. Option A fails to conclude why the brand has set up its production facilities in this town only. Demands of the consumers may have been met through production taking place in other towns also.

Geography: CUET Mock Test - 10 - Question 7

Geography: CUET Mock Test - 10 - Question 38

Which of the following statement is incorrect?

Detailed Solution for Geography: CUET Mock Test - 10 - Question 38

 

  • Ganga–Brahmaputra plain of India:
    • Ganga–Brahmaputra plain of India are drained by Ganga and Brahmaputra rivers.
    • Due to the availability of water and other resources, these plains are one of the overpopulated regions of India. Hence statement 1 is correct.
    • The combined population density in the states of Uttar Pradesh, Bihar, West Bengal, and Assam is higher than the national average.
    • These states lie in the area of Ganga–Brahmaputra plains.
  • Water availability in India:
    • India has only a four percent water share of the world's fresh rainwater resources.
    • So, there is a basic necessity to save, reuse and repurpose.
    • When India became independent, the availability of water was 5,000 liters per capita now it has become 1,100 liters. Hence statement 2 is correct.
    • There is a basic decline in the availability of water due to human and cattle population growth.
  • Shelterbelts: shelterbelts are strips of vegetation composed of trees and shrubs grown along the coasts to protect coastal areas from high-velocity winds and also from devastations like the ones caused by the tsunami. Hence statement 3 is correct.
  • Human interference and climate change: Human interference and changes in climate will further deteriorate the natural ecosystem. Hence statement 4 is incorrect.
    • Climate is an important environmental influence on ecosystems.
    • Changing climate affects ecosystems in a variety of ways.
    • For example, warming may force species to migrate to higher latitudes or higher elevations where temperatures are more conducive to their survival.\
    • Similarly, as the sea level rises, saltwater intrusion into a freshwater system may force some key species to relocate or die, thus removing predators or prey that are critical in the existing food chain.
    • Human impact on the environment or anthropogenic impact on the environment includes changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans, including global warming, environmental degradation (such as ocean acidification), mass extinction, and biodiversity loss, ecological crisis, and ecological collapse. 
Geography: CUET Mock Test - 10 - Question 39

Which of the fallowing can be a safe construction practice to mitigate landslide hazards?

Detailed Solution for Geography: CUET Mock Test - 10 - Question 39

Landslides:

  • A landslide is defined as the movement of a mass of rock, debris, or earth down a slope.
  • Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity.
  • The term "landslide" encompasses five modes of slope movement: falls, topples, slides, spreads, and flows.
  • These are further subdivided by the type of geologic material (bedrock, debris, or earth).
  • Debris flows (commonly referred to as mudflows or mudslides) and rockfalls are examples of common landslide types.

Causes of Landslides:

  • Almost every landslide has multiple causes. Slope movement occurs when forces acting down-slope which is mainly due to gravity exceed the strength of the earth materials that compose the slope.
  • Causes include factors that increase the effects of down-slope forces and factors that contribute to low or reduced strength. 
  • Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in groundwater, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.
  • Human activity, such as agriculture and construction, can increase the risk of a landslide. Irrigation, deforestation, excavation, and water leakage are some of the common activities that can help destabilize, or weaken, a slope.
  • Earthquake shaking and other factors can also induce landslides underwater. 
  • The loss of forest vegetation leads to a reduction in soil cohesion and a decrease in the shear strength of the soil profile. As a result, the slope becomes more susceptible to landslides, and the return time of landslides decreases. When a landslide removes the soil profile, there may not be adequate time for seedlings to grow and enhance soil stability.

From the above discussion, it can be concluded that heavy metal road in a mountain valley, multi-storey building and dam building is not a safe construction practice at landslide-prone areas.
