  2. Salinization

  3. Erosion

  4. Wetland loss
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Wetland loss occurs when wetlands are drained or filled for other uses, such as agriculture, development, or mining. Wetlands provide a variety of important ecosystem services, including flood control, water filtration, and habitat for wildlife.

Multiple choice

What is the primary cause of soil sealing?

  1. Deforestation

  2. Agriculture

  3. Mining

  4. Urbanization
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Soil sealing occurs when soil is covered with impermeable materials, such as concrete or asphalt. This can prevent water and air from infiltrating the soil and can lead to a variety of problems, including flooding, erosion, and loss of soil fertility.

  1. Soil erosion

  2. Deforestation

  3. Overgrazing

  4. Climate change

  5. Lack of political will
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Lack of political will is not a challenge faced in soil conservation efforts in India. The government has implemented a number of policies and programs aimed at promoting soil conservation. However, soil erosion, deforestation, overgrazing, and climate change are all challenges that need to be addressed in order to achieve sustainable soil management.

Multiple choice

Which of the following is a major cause of deforestation?

  1. Forest fires

  2. Natural disasters

  3. Agricultural expansion

  4. Urban development
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Agricultural expansion, particularly for large-scale farming, is a major cause of deforestation, as forests are cleared to make way for agricultural land.
