Front

What is beach erosion?

Back

Beach erosion is the process by which coastal land is worn away by the action of waves, currents, and tides.

Front

How can planting vegetation help prevent beach erosion?

Back

Planting vegetation on beach dunes helps stabilize the sand and soil, reducing the impact of wind and water erosion.

Front

Front

What is the purpose of a storm drain?

Back

A storm drain is designed to carry excess rainwater away from streets and low-lying areas to prevent flooding.

Front

What is soil runoff?

Back

Soil runoff is the movement of soil and water from higher ground to lower ground, often caused by rain or irrigation.

Front

How do dams help control floods?

Back

Dams store excess water during heavy rainfall, releasing it slowly to prevent downstream flooding.

Front

What is the difference between a dam and a levee?

Back

A dam is a barrier that holds back water, while a levee is an embankment built to prevent the overflow of a river.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's crust that move and interact with each other, causing earthquakes and volcanic activity.

Front

What is the impact of construction on soil loss?

Back

Construction can increase soil loss by disturbing the land and reducing vegetation that holds soil in place.
