D Correct answer
Explanation

Deforestation is the process of cutting or removal of forest to fulfill the need of the population. It has many negative impacts on the environment such as loss of species, soil erosion and reduces rainfall. The tree absorbs water from soil for photosynthesis and produces water vapor that is released into the atmosphere which in turn causes rainfall. If there will be less number of the tree then rainfall will also decrease. Plants absorb carbon dioxide (greenhouse gas) for photosynthesis and releases oxygen. Greenhouse gases absorbs the solar energy and increase the earth's temperature is called as global warming. Thus, the correct answer is option D.

Multiple choice
  1. removal of vegetation

  2. forest fires

  3. earthquakes

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mass wasting is triggered by factors that destabilize slopes, including the removal of vegetation (which holds soil), forest fires (which destroy vegetation), and earthquakes (which shake the ground).

Multiple choice
  1. famine

  2. flooding and mudslides

  3. spread of disease

  4. monsoons

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Deforestation removes the natural vegetation that absorbs rainfall and stabilizes soil. This loss of ground cover significantly increases the risk of flooding and mudslides during heavy rains.

Multiple choice
  1. land revenue policies

  2. industrialization

  3. commercialization of agriculture

  4. railroad development

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The commercialization of agriculture forced farmers to clear forests to plant cash crops like indigo, cotton, and tea, which depleted soil nutrients and accelerated deforestation.

Multiple choice
  1. using fertilizers to grow food

  2. clearing trees and overgrazing of livestock

  3. too much rain

  4. using farm machinery

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Desertification is primarily caused by human activities such as deforestation, overgrazing, and unsustainable farming practices that strip the land of vegetation and expose the soil to erosion.

Multiple choice
  1. removal of dirt

  2. removal of rivers

  3. removal of seasons

  4. removal of vegetation

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Desertification is the process by which fertile land becomes desert. The removal of vegetation (deforestation or overgrazing) leaves the soil exposed to erosion, accelerating this process.

Multiple choice
  1. desertification

  2. abundance

  3. malnutrition

  4. deforestation

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When monsoon rains are lighter than expected, crops fail due to lack of water. This leads to food shortages and, consequently, malnutrition among the population.

What is cause of 'forest' decline?

  1. Acid loving moss

  2. Deforestation

  3. Pollution

  4. Climate Change

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Acid-loving mosses, such as Sphagnum, can create highly acidic and waterlogged conditions in the soil. This prevents proper aeration and nutrient uptake by tree roots, eventually leading to the decline and death of surrounding forest trees.

Multiple choice
  1. Increase level of Co2

  2. Increase pollution

  3. Global warming

  4. All the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Deforestation leads to fewer trees to absorb carbon dioxide, which increases CO2 levels in the atmosphere. This accumulation of CO2 contributes to global warming and overall environmental degradation and pollution.

Multiple choice
  1. Planting more trees

  2. Designing a forest

  3. Clearing forest for our use

  4. Demanding for forest

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Deforestation is the purposeful clearing of forested land, often to make way for agriculture, pasture, or urban development. Planting more trees is called afforestation or reforestation.

Multiple choice
  1. Food Surplus

  2. Specialization

  3. Disease

  4. Wild Fires

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The transition to agriculture and animal domestication brought humans into closer, more frequent contact with animals and larger settled populations. This environment facilitated the mutation and spread of zoonotic diseases, which was a major negative consequence of early settled life.
