Lesson 5:2 Erosion and Deposition

Front

What is gully erosion?

Back

Gully erosion is the erosion by running water that creates deep and wide channels in the landscape.

Front

What is a good wind barrier on a farm?

Back

A row of trees serves as an effective wind barrier on a farm.

Front

What type of water erosion causes significant changes along a coast?

Back

Wave action is the type of water erosion that causes the most changes along a coast.

Front

What is weathering?

Back

Weathering is the chemical or mechanical process that breaks down and changes rocks on or near Earth's surface.

Front

What is erosion?

Back

Erosion is the removal and transport of weathered material from one location to another.

Front

What is deposition?

Back

Deposition is the process by which sediment and other materials are laid down or deposited in a new location.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, leading to their breakdown.

Front

What is rill erosion?

Back

Rill erosion is the removal of soil by concentrated water running through small channels.

Front

What is the role of vegetation in erosion control?

Back

Vegetation helps to anchor soil in place, reducing the risk of erosion by wind and water.
