Deforestation and Land Degradation Questions

Multiple choice geography secondary sector : industry generation of electricity exploration and conservation of minerals irrigation and power

Deforestation is caused due to _____.

  1. Grazing

  2. Mining

  3. Cultivation

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The cutting down of trees and clearing off the forests is known as deforestation. Deforestation is caused due to following reasons:- 

  • Requirement of more land for housing and urbanization
  • Harvesting timber to create commercial items such as paper, furniture and homes
  • Cattle grazing
  • Mining activities
  • Cultivation
  • Burning trees and clear cutting

Multiple choice evs - i the environment and us pollution of soil degradation of land damaging the forests

Which of the following is an effect of deforestation?

  1. Water pollution

  2. Greenhouse effect

  3. Outbreak of diseases

  4. Extinction of aquatic life
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

If deforestation is performed, there will be no trees so, the amount of the greenhouse gasses will increase in the atmosphere. These greenhouse gasses trap heat from the infrared radiation in the atmosphere and increases the atmosphere's temperature i.e, global warming. 

Thus, the correct answer is option B. 

Multiple choice zoology soil pollution pollution of soil degradation of land damaging the forests

All of these are a result of land degradation except 

  1. Soil erosion

  2. Extinction of plant species

  3. Endangered animals

  4. Clear cutting forests

  5. Ozone depletion
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Land degradation is the loss in quality of natural land areas due to pollution.
A. Due to land degradation, there is deterioration in soil structure due to which soil particles can't bind to each other tightly. Hence there is soil erosion i.e. removal of upper fertile layer of soil due to flood, wind or any other natural calamity.
B. Due to land degradation, many plant species have become extinct because there is loss of soil nutrients which are essential for plants growth.
C. Animals are getting endangered as their habitat is also being lost due to land degradation.
D. Clear cutting of forests doesn't occur due to land degradation. It's the activity of mankind.
E. Ozone layer depletion occurs due to the halo compounds that are released from the degrading land.
Hence, clear cutting forests is not the result of land degradation.
So, the correct answer is 'Clear cutting forests'.
Multiple choice evs - i the environment and us pollution of soil degradation of land damaging the forests

Which of the following is/are caused due to deforestation?

  1. Soil erosion

  2. Depletion of water in the catchment areas

  3. Global warming

  4. All of these
Reveal answer Fill a bubble to check yourself
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

Which of the following is a preceding cause of mass wasting?

  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

What was the impact of deforestation?

  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

This process damaged the Indian soil and resulted in deforestation.

  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

What causes desertification?

  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

Major causes of desertification in South Asia are climate change and...

  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

What is an effect of light monsoon rains?

  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.

Multiple choice botany pictorial feature of plant kingdom classification of bryophytes types of bryophytes bryophyta

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.
