What are wetlands?

  1. Areas of land that are permanently or seasonally flooded

  2. Areas of land that are covered with trees

  3. Areas of land that are used for agriculture

  4. Areas of land that are covered with snow


Correct Option: A
Explanation:

Wetlands are areas of land that are permanently or seasonally flooded, either naturally or artificially. They include swamps, marshes, bogs, and fens.

What is the role of wetlands in the global carbon cycle?

  1. They are a source of carbon dioxide

  2. They are a sink for carbon dioxide

  3. They have no role in the global carbon cycle

  4. They release methane, a greenhouse gas


Correct Option: B
Explanation:

Wetlands are a sink for carbon dioxide, meaning they absorb more carbon dioxide than they release. This is due to the presence of plants and microorganisms that use carbon dioxide for photosynthesis and growth.

How does climate change affect wetlands?

  1. It increases the frequency and severity of droughts

  2. It increases the frequency and severity of floods

  3. It increases the temperature of wetlands

  4. All of the above


Correct Option: D
Explanation:

Climate change affects wetlands in a number of ways, including increasing the frequency and severity of droughts, floods, and wildfires, as well as increasing the temperature of wetlands.

What are the consequences of wetland loss due to climate change?

  1. Loss of biodiversity

  2. Increased flooding

  3. Reduced water quality

  4. All of the above


Correct Option: D
Explanation:

Wetland loss due to climate change has a number of consequences, including loss of biodiversity, increased flooding, reduced water quality, and increased greenhouse gas emissions.

What can be done to protect wetlands from climate change?

  1. Reduce greenhouse gas emissions

  2. Restore and protect existing wetlands

  3. Create new wetlands

  4. All of the above


Correct Option: D
Explanation:

To protect wetlands from climate change, we need to reduce greenhouse gas emissions, restore and protect existing wetlands, and create new wetlands.

Which of the following is a type of wetland?

  1. Swamp

  2. Desert

  3. Forest

  4. Grassland


Correct Option: A
Explanation:

A swamp is a type of wetland that is characterized by its waterlogged soil and the presence of trees and shrubs.

What is the primary source of methane emissions from wetlands?

  1. Decomposition of organic matter

  2. Volcanic activity

  3. Industrial processes

  4. Transportation


Correct Option: A
Explanation:

The primary source of methane emissions from wetlands is the decomposition of organic matter by microorganisms in the absence of oxygen.

How do wetlands contribute to flood control?

  1. By absorbing excess water

  2. By releasing water slowly

  3. By creating natural barriers

  4. All of the above


Correct Option: D
Explanation:

Wetlands contribute to flood control by absorbing excess water, releasing water slowly, and creating natural barriers that slow down the flow of water.

What is the term used to describe the process by which wetlands remove pollutants from water?

  1. Bioremediation

  2. Phytoremediation

  3. Constructed wetlands

  4. Water filtration


Correct Option: B
Explanation:

Phytoremediation is the term used to describe the process by which wetlands remove pollutants from water using plants.

Which of the following is a major threat to wetlands worldwide?

  1. Climate change

  2. Pollution

  3. Habitat destruction

  4. All of the above


Correct Option: D
Explanation:

Climate change, pollution, and habitat destruction are all major threats to wetlands worldwide.

What percentage of the Earth's surface is covered by wetlands?

  1. 1%

  2. 5%

  3. 10%

  4. 20%


Correct Option: B
Explanation:

Wetlands cover approximately 5% of the Earth's surface.

Which of the following is a type of wetland that is characterized by its high salinity?

  1. Salt marsh

  2. Freshwater marsh

  3. Bog

  4. Fen


Correct Option: A
Explanation:

A salt marsh is a type of wetland that is characterized by its high salinity and the presence of salt-tolerant plants.

What is the term used to describe the process by which wetlands are created or restored?

  1. Wetland restoration

  2. Wetland creation

  3. Wetland mitigation

  4. All of the above


Correct Option: D
Explanation:

Wetland restoration, wetland creation, and wetland mitigation are all terms used to describe the process by which wetlands are created or restored.

Which of the following is a type of wetland that is characterized by its floating vegetation?

  1. Bog

  2. Fen

  3. Swamp

  4. Marsh


Correct Option: D
Explanation:

A marsh is a type of wetland that is characterized by its floating vegetation, such as cattails and reeds.

What is the term used to describe the process by which wetlands store carbon?

  1. Carbon sequestration

  2. Carbon storage

  3. Carbon capture

  4. All of the above


Correct Option: D
Explanation:

Carbon sequestration, carbon storage, and carbon capture are all terms used to describe the process by which wetlands store carbon.
