Lesson Check: Weathering, Erosion, & Deposition

Front

What is weathering?

Back

The process of breaking down rocks into smaller pieces through natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

The process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is deposition?

Back

The process where materials transported by erosion are dropped off in a new location, forming new landforms.

Front

What is an alluvial fan?

Back

A landform created by the deposition of sediment from a river as it flows out of a mountain range onto a flatter area.

Front

How are sand dunes formed?

Back

Eroded sand is carried by the wind and deposited in mounds, forming sand dunes.

Front

What is a delta?

Back

A landform created at the mouth of a river where it meets a body of water, formed by the deposition of sediment carried by the river.

Front

What role does wind play in erosion?

Back

Wind can carry small particles of soil and sand away from one location and deposit them in another, contributing to erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials to a new location.

Front

What is mechanical weathering?

Back

The physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical reactions, often involving water and minerals.
