  3. Groundwater recharge

  4. All of the above


Correct Option: D
Explanation:

Wetlands perform multiple functions in the water cycle, including water filtration, flood control, and groundwater recharge.

Which of the following is NOT a type of wetland?

  1. Bog

  2. Fen

  3. Marsh

  4. Desert


Correct Option: D
Explanation:

Bogs, fens, and marshes are all types of wetlands, while deserts are not.

What is the main source of water for wetlands?

  1. Rainfall

  2. Groundwater

  3. Surface runoff

  4. All of the above


Correct Option: D
Explanation:

Wetlands can receive water from rainfall, groundwater, and surface runoff.

How do wetlands help control floods?

  1. By absorbing and storing excess water

  2. By slowing down the flow of water

  3. By providing natural barriers against flooding

  4. All of the above


Correct Option: D
Explanation:

Wetlands help control floods by absorbing and storing excess water, slowing down the flow of water, and providing natural barriers against flooding.

What is the role of wetlands in groundwater recharge?

  1. They allow water to infiltrate the ground

  2. They help purify groundwater

  3. They store groundwater for future use

  4. All of the above


Correct Option: D
Explanation:

Wetlands play a crucial role in groundwater recharge by allowing water to infiltrate the ground, purifying groundwater, and storing groundwater for future use.

Which of the following is NOT a benefit of wetlands?

  1. Water filtration and purification

  2. Flood control and storage

  3. Habitat for wildlife

  4. Source of food and medicine


Correct Option: D
Explanation:

While wetlands provide many benefits, they are not typically a direct source of food and medicine.

What is the main threat to wetlands worldwide?

  1. Pollution

  2. Climate change

  1. Bog

  2. Fen

  3. Marsh

  4. Swamp


Correct Option: A
Explanation:

Bogs are characterized by acidic water and a lack of nutrients.

What is the primary source of nutrients for wetlands?

  1. Rainfall

  2. Groundwater

  3. Surface runoff

  4. Decomposition of organic matter


Correct Option: D
Explanation:

The primary source of nutrients for wetlands is the decomposition of organic matter.

Which type of wetland is dominated by trees and shrubs?

  1. Bog

  2. Fen

  3. Swamp

  4. Marsh


Correct Option: C
