What is the primary cause of coastal erosion due to climate change?

  1. Rising sea levels

  2. Increased storm intensity

  3. Changes in sediment supply

  4. Human activities


Correct Option: A
Explanation:

Rising sea levels, primarily driven by thermal expansion of ocean water and melting glaciers, are the main cause of coastal erosion due to climate change.

How does increased storm intensity contribute to coastal erosion?

  1. Stronger waves and storm surges

  2. Increased precipitation and flooding

  3. Higher wind speeds

  4. All of the above


Correct Option: D
Explanation:

Increased storm intensity, including stronger waves and storm surges, higher wind speeds, and increased precipitation and flooding, all contribute to coastal erosion.

What is the impact of coastal erosion on coastal communities?

  1. Loss of land and property

  2. Damage to infrastructure

  3. Displacement of people

  4. All of the above


Correct Option: D
Explanation:

Coastal erosion can lead to the loss of land and property, damage to infrastructure, and displacement of people, posing significant challenges to coastal communities.

Which coastal ecosystem is particularly vulnerable to erosion caused by climate change?

  1. Coral reefs

  2. Mangrove forests

  3. Salt marshes

  4. All of the above


Correct Option: D
Explanation:

Coral reefs, mangrove forests, and salt marshes are all coastal ecosystems that are particularly vulnerable to erosion caused by climate change due to their sensitivity to changes in sea level and wave action.

What is a potential adaptation strategy to mitigate the impacts of coastal erosion?

  1. Building seawalls and other hard structures

  2. Restoring and protecting natural ecosystems

  3. Relocating coastal communities

  4. A combination of the above


Correct Option: D
Explanation:

A combination of strategies, including building seawalls and other hard structures, restoring and protecting natural ecosystems, and relocating coastal communities, may be necessary to mitigate the impacts of coastal erosion.

How can coastal communities adapt to the impacts of sea-level rise?

  1. Elevate buildings and infrastructure

  2. Construct seawalls and other barriers

  3. Restore and protect natural ecosystems

  4. All of the above


Correct Option: D
Explanation:

Coastal communities can adapt to the impacts of sea-level rise by elevating buildings and infrastructure, constructing seawalls and other barriers, and restoring and protecting natural ecosystems.

What are some of the challenges associated with adapting to coastal erosion?

  1. High costs of adaptation measures

  2. Limited availability of suitable land for relocation

  3. Resistance from local communities

  4. All of the above


Correct Option: D
Explanation:

Adapting to coastal erosion can be challenging due to high costs of adaptation measures, limited availability of suitable land for relocation, and resistance from local communities.

What role can governments play in addressing coastal erosion?

  1. Developing and implementing coastal management policies

  2. Providing financial assistance to coastal communities

  3. Investing in research and monitoring

  4. All of the above


Correct Option: D
Explanation:

Governments can play a crucial role in addressing coastal erosion by developing and implementing coastal management policies, providing financial assistance to coastal communities, and investing in research and monitoring.

What are some of the potential consequences of coastal erosion for marine ecosystems?

  1. Loss of biodiversity

  2. Disruption of food chains

  3. Increased vulnerability to pollution

  4. All of the above


Correct Option: D
Explanation:

Coastal erosion can have significant consequences for marine ecosystems, including loss of biodiversity, disruption of food chains, and increased vulnerability to pollution.

How can coastal communities reduce their contribution to coastal erosion?

  1. Reducing greenhouse gas emissions

  2. Implementing sustainable land use practices

  3. Protecting and restoring natural ecosystems

  4. All of the above


Correct Option: D
Explanation:

Coastal communities can reduce their contribution to coastal erosion by reducing greenhouse gas emissions, implementing sustainable land use practices, and protecting and restoring natural ecosystems.

What is the role of mangroves in mitigating coastal erosion?

  1. They stabilize the shoreline with their roots

  2. They reduce wave energy and erosion

  3. They provide a habitat for marine life

  4. All of the above


Correct Option: D
Explanation:

Mangroves play a crucial role in mitigating coastal erosion by stabilizing the shoreline with their roots, reducing wave energy and erosion, and providing a habitat for marine life.

How can coral reefs contribute to coastal protection?

  1. They break waves and reduce erosion

  2. They provide a habitat for marine life

  3. They help maintain water quality

  4. All of the above


Correct Option: D
Explanation:

Coral reefs contribute to coastal protection by breaking waves and reducing erosion, providing a habitat for marine life, and helping maintain water quality.

What is the significance of salt marshes in coastal erosion management?

  1. They trap sediment and stabilize the shoreline

  2. They provide a habitat for wildlife

  3. They help filter pollutants from water

  4. All of the above


Correct Option: D
Explanation:

Salt marshes play a significant role in coastal erosion management by trapping sediment and stabilizing the shoreline, providing a habitat for wildlife, and helping filter pollutants from water.

How can beach nourishment help address coastal erosion?

  1. It replenishes sand on eroded beaches

  2. It protects coastal infrastructure

  3. It improves water quality

  4. All of the above


Correct Option: D
Explanation:

Beach nourishment involves replenishing sand on eroded beaches, protecting coastal infrastructure, and improving water quality.

What is the role of groynes and jetties in coastal erosion management?

  1. They trap sediment and help build up beaches

  2. They protect coastal infrastructure

  3. They help maintain navigation channels

  4. All of the above


Correct Option: D
Explanation:

Groynes and jetties are structures built to trap sediment and help build up beaches, protect coastal infrastructure, and maintain navigation channels.
