What is the primary function of wetlands in mitigating the impacts of natural hazards?

  1. Filtering pollutants from water

  2. Providing habitat for wildlife

  3. Reducing the risk of flooding

  4. Storing carbon dioxide


Correct Option: C
Explanation:

Wetlands act as natural sponges, absorbing and storing floodwaters, thereby reducing the risk of flooding in nearby areas.

Which type of wetland is particularly effective in reducing coastal erosion?

  1. Salt marshes

  2. Mangroves

  3. Freshwater marshes

  4. Bogs


Correct Option: A
Explanation:

Salt marshes, with their dense vegetation and intricate root systems, help stabilize coastlines and reduce erosion caused by waves and storms.

How do wetlands contribute to disaster risk reduction in urban areas?

  1. By providing recreational opportunities

  2. By enhancing property values

  3. By reducing air pollution

  4. By absorbing stormwater runoff


Correct Option: D
Explanation:

Wetlands in urban areas help reduce the risk of flooding by absorbing stormwater runoff, preventing it from overwhelming drainage systems and causing urban flooding.

What is the term used to describe the process of restoring degraded wetlands to their natural state?

  1. Wetland mitigation

  2. Wetland restoration

  3. Wetland creation

  4. Wetland enhancement


Correct Option: B
Explanation:

Wetland restoration involves restoring degraded wetlands to their natural state, improving their ecological functions and biodiversity.

Which international agreement specifically addresses the conservation and wise use of wetlands?

  1. The Ramsar Convention

  2. The Kyoto Protocol

  3. The Paris Agreement

  4. The Convention on Biological Diversity


Correct Option: A
Explanation:

The Ramsar Convention, also known as the Convention on Wetlands, is an international treaty that provides the framework for the conservation and wise use of wetlands.

What is the primary reason for the loss and degradation of wetlands worldwide?

  1. Climate change

  2. Pollution

  3. Overpopulation

  4. Land conversion


Correct Option: D
Explanation:

Land conversion for agriculture, development, and other human activities is the primary cause of wetland loss and degradation worldwide.

Which type of wetland is known for its ability to filter pollutants and improve water quality?

  1. Bogs

  2. Fens

  3. Marshes

  4. Swamps


Correct Option: C
Explanation:

Marshes, with their dense vegetation and microbial communities, play a crucial role in filtering pollutants and improving water quality.

How do wetlands contribute to carbon sequestration and climate change mitigation?

  1. By releasing methane, a greenhouse gas

  2. By absorbing carbon dioxide from the atmosphere

  3. By reducing energy consumption

  4. By promoting sustainable agriculture


Correct Option: B
Explanation:

Wetlands, particularly peatlands, are significant carbon sinks, absorbing carbon dioxide from the atmosphere and storing it in their organic matter.

Which type of wetland is characterized by acidic conditions and a lack of oxygen?

  1. Bogs

  2. Fens

  3. Marshes

  4. Swamps


Correct Option: A
Explanation:

Bogs are wetlands with acidic conditions, low nutrient levels, and a lack of oxygen, creating a unique ecosystem adapted to these harsh conditions.

What is the term used to describe the process of creating new wetlands in areas where they have been lost or degraded?

  1. Wetland mitigation

  2. Wetland restoration

  3. Wetland creation

  4. Wetland enhancement


Correct Option: C
Explanation:

Wetland creation involves establishing new wetlands in areas where they have been lost or degraded, typically for ecological restoration or mitigation purposes.

Which type of wetland is known for its ability to support a diverse array of plant and animal species?

  1. Bogs

  2. Fens

  3. Marshes

  4. Swamps


Correct Option: D
Explanation:

Swamps, with their rich organic matter and abundant vegetation, provide diverse habitats for a wide range of plant and animal species.

How do wetlands contribute to flood control and water storage?

  1. By releasing water into rivers and streams

  2. By absorbing and storing floodwaters

  3. By increasing the rate of evaporation

  4. By reducing the amount of rainfall


Correct Option: B
Explanation:

Wetlands act as natural sponges, absorbing and storing floodwaters, reducing the risk of flooding downstream and helping to maintain a steady flow of water during dry periods.

Which type of wetland is characterized by a high concentration of dissolved salts?

  1. Bogs

  2. Fens

  3. Salt marshes

  4. Swamps


Correct Option: C
Explanation:

Salt marshes are wetlands that are influenced by tides and have a high concentration of dissolved salts, creating a unique ecosystem adapted to saline conditions.

What is the term used to describe the process of improving the ecological functions of existing wetlands?

  1. Wetland mitigation

  2. Wetland restoration

  3. Wetland creation

  4. Wetland enhancement


Correct Option: D
Explanation:

Wetland enhancement involves improving the ecological functions of existing wetlands by restoring degraded areas, removing invasive species, or implementing management practices that promote wetland health.

How do wetlands contribute to groundwater recharge and water quality improvement?

  1. By releasing pollutants into groundwater

  2. By reducing the amount of water available for drinking

  3. By filtering pollutants and replenishing groundwater

  4. By increasing the rate of evaporation


Correct Option: C
Explanation:

Wetlands act as natural filters, removing pollutants from water and replenishing groundwater aquifers, contributing to improved water quality and availability.
