What are wetlands?

  1. Areas of land that are covered in water for all or part of the year.

  2. Areas of land that are covered in forest.

  3. Areas of land that are covered in desert.

  4. Areas of land that are covered in mountains.


Correct Option: A
Explanation:

Wetlands are areas of land that are covered in water for all or part of the year. They can be natural or man-made, and they include swamps, marshes, bogs, and fens.

What are mangroves?

  1. Trees that grow in salt water.

  2. Trees that grow in fresh water.

  3. Trees that grow in desert.

  4. Trees that grow in mountains.


Correct Option: A
Explanation:

Mangroves are trees that grow in salt water. They are found in tropical and subtropical regions of the world, and they play an important role in protecting coastal areas from erosion and storm damage.

How do wetlands and mangroves help to reduce the risk of disasters?

  1. They absorb floodwaters and reduce the risk of flooding.

  2. They filter pollutants and improve water quality.

  3. They provide habitat for wildlife and support biodiversity.

  4. All of the above.


Correct Option: D
Explanation:

Wetlands and mangroves provide a number of benefits that help to reduce the risk of disasters. They absorb floodwaters and reduce the risk of flooding, they filter pollutants and improve water quality, and they provide habitat for wildlife and support biodiversity.

What are some of the threats to wetlands and mangroves?

  1. Pollution

  2. Climate change

  3. Deforestation

  4. All of the above.


Correct Option: D
Explanation:

Wetlands and mangroves are threatened by a number of human activities, including pollution, climate change, and deforestation. Pollution can contaminate the water and soil in wetlands, making them uninhabitable for wildlife. Climate change is causing sea levels to rise, which is threatening coastal wetlands. Deforestation is removing trees that help to protect wetlands from erosion and storm damage.

What can be done to protect wetlands and mangroves?

  1. Reduce pollution.

  2. Mitigate climate change.

  3. Protect forests.

  4. All of the above.


Correct Option: D
Explanation:

There are a number of things that can be done to protect wetlands and mangroves. These include reducing pollution, mitigating climate change, and protecting forests. Reducing pollution can help to improve water quality and make wetlands more habitable for wildlife. Mitigating climate change can help to slow the rate of sea level rise and protect coastal wetlands. Protecting forests can help to reduce erosion and storm damage to wetlands.

Wetlands and mangroves are important ecosystems that provide a number of benefits to humans and the environment. What are some of these benefits?

  1. They help to reduce the risk of flooding.

  2. They filter pollutants and improve water quality.

  3. They provide habitat for wildlife and support biodiversity.

  4. They help to mitigate climate change.

  5. All of the above.


Correct Option: E
Explanation:

Wetlands and mangroves provide a number of benefits to humans and the environment. They help to reduce the risk of flooding by absorbing floodwaters and reducing the force of waves. They filter pollutants and improve water quality by removing sediment and nutrients from the water. They provide habitat for wildlife and support biodiversity by providing food, shelter, and breeding grounds for a variety of plants and animals. They also help to mitigate climate change by absorbing carbon dioxide and releasing oxygen.

What are some of the threats to wetlands and mangroves?

  1. Pollution

  2. Climate change

  3. Deforestation

  4. All of the above.


Correct Option: D
Explanation:

Wetlands and mangroves are threatened by a number of human activities, including pollution, climate change, and deforestation. Pollution can contaminate the water and soil in wetlands, making them uninhabitable for wildlife. Climate change is causing sea levels to rise, which is threatening coastal wetlands. Deforestation is removing trees that help to protect wetlands from erosion and storm damage.

What can be done to protect wetlands and mangroves?

  1. Reduce pollution.

  2. Mitigate climate change.

  3. Protect forests.

  4. All of the above.


Correct Option: D
Explanation:

There are a number of things that can be done to protect wetlands and mangroves. These include reducing pollution, mitigating climate change, and protecting forests. Reducing pollution can help to improve water quality and make wetlands more habitable for wildlife. Mitigating climate change can help to slow the rate of sea level rise and protect coastal wetlands. Protecting forests can help to reduce erosion and storm damage to wetlands.

How do wetlands and mangroves help to protect coastal communities from storm surges?

  1. They absorb the energy of the waves.

  2. They reduce the height of the waves.

  3. They slow the speed of the waves.

  4. All of the above.


Correct Option: D
Explanation:

Wetlands and mangroves help to protect coastal communities from storm surges by absorbing the energy of the waves, reducing the height of the waves, and slowing the speed of the waves. This helps to reduce the damage caused by storm surges and can save lives.

How do wetlands and mangroves help to protect coastal communities from erosion?

  1. They absorb the energy of the waves.

  2. They reduce the height of the waves.

  3. They slow the speed of the waves.

  4. They trap sediment and build up the shoreline.


Correct Option: D
Explanation:

Wetlands and mangroves help to protect coastal communities from erosion by trapping sediment and building up the shoreline. This helps to create a natural buffer between the land and the sea, which can help to reduce the damage caused by waves and storms.

How do wetlands and mangroves help to support biodiversity?

  1. They provide habitat for a variety of plants and animals.

  2. They provide food and shelter for wildlife.

  3. They help to maintain water quality.

  4. All of the above.


Correct Option: D
Explanation:

Wetlands and mangroves help to support biodiversity by providing habitat for a variety of plants and animals, providing food and shelter for wildlife, and helping to maintain water quality. This makes them important ecosystems for a wide range of species.

How do wetlands and mangroves help to mitigate climate change?

  1. They absorb carbon dioxide from the atmosphere.

  2. They release oxygen into the atmosphere.

  3. They help to regulate the Earth's temperature.

  4. All of the above.


Correct Option: D
Explanation:

Wetlands and mangroves help to mitigate climate change by absorbing carbon dioxide from the atmosphere, releasing oxygen into the atmosphere, and helping to regulate the Earth's temperature. This makes them important ecosystems for helping to reduce the impacts of climate change.

What are some of the challenges to conserving wetlands and mangroves?

  1. Pollution

  2. Climate change
