FCHS Earth Systems: SES3.b and c Flashcard

Front

How do rivers form?

Back

Rivers form when water moves from higher to lower elevation.

Front

How does rainwater contribute to erosion?

Back

Rainwater contributes to erosion by physically weathering rocks and moving sediment downhill.

Front

What increases the chance of landslides?

Back

Building on unstable slopes, undercutting the base of slopes to build roads, and removing vegetation from steep slopes increase the chance of landslides.

Front

What type of valley is carved by a river's fast-moving headwaters?

Back

A V-shaped valley is carved by a river's fast-moving headwaters.

Front

What forms when a river meets the ocean?

Back

A delta forms when a river meets the ocean.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is sediment?

Back

Sediment is solid material that is moved and deposited by water, wind, or ice.

Front

What role do trees play in preventing landslides?

Back

Trees help stabilize soil with their roots, reducing the risk of landslides.

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, characterized by sediment deposition.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks and minerals, while erosion is the movement of those materials from one location to another.
