Geomorphic Processes Questions

Multiple choice

What are some of the human activities that can contribute to coastal erosion?

  1. Construction of dams and levees

  2. Dredging

  3. Beach nourishment

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Human activities can contribute to coastal erosion in a number of ways. The construction of dams and levees can alter the flow of water and sediment, which can lead to coastal erosion. Dredging can also contribute to coastal erosion by removing sediment from the coastline. Beach nourishment is a process by which sand is added to a beach to help protect it from erosion. However, beach nourishment can also have negative effects, such as the loss of habitat for marine life.

Multiple choice

What are some of the ways to protect against coastal erosion?

  1. Building seawalls and groins

  2. Restoring wetlands

  3. Beach nourishment

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

There are a number of ways to protect against coastal erosion, including building seawalls and groins, restoring wetlands, and beach nourishment. Seawalls and groins are structures that are built to protect the coastline from erosion. Wetlands help to buffer the coastline from waves and storms. Beach nourishment is a process by which sand is added to a beach to help protect it from erosion.

Multiple choice

What is beach nourishment?

  1. A process by which sand is added to a beach to help protect it from erosion.

  2. A process by which wetlands are restored.

  3. A process by which seawalls and groins are built.

  4. None of the above
