Multiple choice

Mangroves are particularly effective in carbon sequestration due to their:

  1. High rate of photosynthesis

  2. Extensive root systems

  3. Ability to store carbon in their biomass

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

Mangroves excel in carbon sequestration due to their rapid growth, extensive root systems that trap sediment and organic matter, and their ability to store carbon in their biomass.

Multiple choice

Which of the following is NOT a consequence of mangrove deforestation?

  1. Increased coastal erosion

  2. Loss of biodiversity

  3. Reduced carbon sequestration

  4. Improved water quality
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mangrove deforestation leads to increased coastal erosion, loss of biodiversity, and reduced carbon sequestration. It does not improve water quality.

Multiple choice

What is the impact of overgrazing on grasslands?

  1. Reduced biodiversity

  2. Soil erosion

  3. Increased fire risk

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

Overgrazing can have a number of negative impacts on grasslands, including reduced biodiversity, soil erosion, increased fire risk, and decreased productivity.

Multiple choice

What is the primary cause of desertification in India?

  1. Deforestation

  2. Overgrazing

  3. Climate Change

  4. Industrialization
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Deforestation is the primary cause of desertification in India, as it reduces vegetation cover and exposes the soil to erosion.

Multiple choice

What are the major economic impacts of desertification in India?

  1. Reduced agricultural productivity

  2. Loss of biodiversity

  3. Increased poverty

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

Desertification in India has multiple economic impacts, including reduced agricultural productivity, loss of biodiversity, increased poverty, and overall economic decline.

Multiple choice

What is the primary cause of coral reef degradation in the Lakshadweep Islands?

  1. Climate change

  2. Pollution

  3. Overfishing

  4. Tourism
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Climate change, particularly rising sea temperatures, poses the most significant threat to coral reefs in the Lakshadweep Islands, leading to coral bleaching and degradation.

Multiple choice

What is the primary cause of ocean acidification?

  1. Deforestation

  2. Volcanic Eruptions

  3. Burning of Fossil Fuels

  4. Natural Disasters
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The burning of fossil fuels releases carbon dioxide into the atmosphere, which is absorbed by the ocean, leading to ocean acidification.

Multiple choice

What are the main environmental challenges facing the Deccan Plateau?

  1. Deforestation

  2. Soil erosion

  3. Water pollution

  4. Air pollution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Deforestation is the main environmental challenge facing the Deccan Plateau, with large areas of forest being cleared for agriculture and development.

Multiple choice

Which of the following is a major cause of deforestation?

  1. Natural disasters

  2. Agricultural expansion

  3. Urban development

  4. Forest fires
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Agricultural expansion is a major cause of deforestation, as forests are cleared to make way for farmland.

Multiple choice

Which of the following is a major cause of soil erosion?

  1. Deforestation

  2. Agricultural practices

  3. Urban development

  4. Mining
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Agricultural practices, such as plowing and overgrazing, can lead to soil erosion.

Multiple choice
