What is coastal erosion?

  1. The process by which waves and currents wear away at the coastline

  2. The process by which sediment is deposited on the coastline

  3. The process by which sea levels rise

  4. The process by which coral reefs are formed


Correct Option: A
Explanation:

Coastal erosion is the process by which waves and currents wear away at the coastline, causing it to recede.

What are the main causes of coastal erosion?

  1. Sea level rise

  2. Storms

  3. Human activities

  4. All of the above


Correct Option: D
Explanation:

Coastal erosion is caused by a combination of factors, including sea level rise, storms, and human activities such as the construction of seawalls and jetties.

How does coastal erosion affect marine life?

  1. It destroys marine habitats

  2. It reduces the food supply for marine life

  3. It makes it more difficult for marine life to reproduce

  4. All of the above


Correct Option: D
Explanation:

Coastal erosion can have a devastating impact on marine life, destroying habitats, reducing the food supply, and making it more difficult for marine life to reproduce.

Which marine species are most vulnerable to coastal erosion?

  1. Coral reefs

  2. Sea turtles

  3. Fish

  4. All of the above


Correct Option: D
Explanation:

Coral reefs, sea turtles, and fish are all marine species that are particularly vulnerable to coastal erosion.

What can be done to reduce coastal erosion?

  1. Build seawalls and jetties

  2. Restore wetlands

  3. Reduce greenhouse gas emissions

  4. All of the above


Correct Option: D
Explanation:

There are a number of things that can be done to reduce coastal erosion, including building seawalls and jetties, restoring wetlands, and reducing greenhouse gas emissions.

What are the long-term consequences of coastal erosion?

  1. Loss of land

  2. Increased flooding

  3. Damage to infrastructure

  4. All of the above


Correct Option: D
Explanation:

Coastal erosion can have a number of long-term consequences, including loss of land, increased flooding, and damage to infrastructure.

How can coastal erosion be managed?

  1. Build seawalls and jetties

  2. Restore wetlands

  3. Reduce greenhouse gas emissions

  4. All of the above


Correct Option: D
Explanation:

Coastal erosion can be managed by a combination of strategies, including building seawalls and jetties, restoring wetlands, and reducing greenhouse gas emissions.

What are some of the challenges associated with managing coastal erosion?

  1. Cost

  2. Environmental impacts

  3. Public opposition

  4. All of the above


Correct Option: D
Explanation:

There are a number of challenges associated with managing coastal erosion, including cost, environmental impacts, and public opposition.

What are some of the most effective ways to protect coastal communities from erosion?

  1. Build seawalls and jetties

  2. Restore wetlands

  3. Reduce greenhouse gas emissions

  4. All of the above


Correct Option: D
Explanation:

The most effective ways to protect coastal communities from erosion include building seawalls and jetties, restoring wetlands, and reducing greenhouse gas emissions.

What are some of the most vulnerable coastal areas in the world?

  1. Low-lying islands
