Multiple choice

What are the effects of coastal erosion?

  1. Loss of land

  2. Damage to infrastructure

  3. Loss of habitat

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Coastal erosion can have a variety of negative effects, including loss of land, damage to infrastructure, and loss of habitat. As the coastline retreats, land is lost, which can displace people and businesses. Coastal erosion can also damage infrastructure, such as roads, bridges, and ports. Finally, coastal erosion can lead to the loss of habitat for plants and animals.

Explanation

Beach nourishment can have a number of negative effects, including disrupting the natural ecosystem of the beach, being expensive, and only being able to be used in areas with a lot of sand.

Multiple choice

What are the main threats to coral reefs?

  1. Climate change

  2. Pollution

  3. Overfishing

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Climate change, pollution, and overfishing are all major threats to coral reefs. Climate change is causing the ocean to become warmer and more acidic, which is harmful to coral reefs. Pollution can also damage coral reefs, and overfishing can reduce the number of fish that eat algae, which can lead to an overgrowth of algae on coral reefs.

Multiple choice
