Weathering, Erosion, or Deposition

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another by natural forces such as water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often occurring when the transporting medium loses energy.

Front

Give an example of weathering.

Back

An example of weathering is when rainwater seeps into cracks in rocks, causing them to break apart over time.

Front

Give an example of erosion.

Back

An example of erosion is a river carrying away soil and rocks from its banks as it flows.

Front

Give an example of deposition.

Back

An example of deposition is when a river slows down and drops off sand and gravel at its mouth, forming a delta.

Front

What role does gravity play in erosion?

Back

Gravity pulls rocks and sediments downhill, contributing to the erosion process.

Front

How does weathering differ from erosion?

Back

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

Front

What are the two main types of weathering?

Back

The two main types of weathering are mechanical weathering (physical breakdown) and chemical weathering (changes in mineral composition).

Front

What is mechanical weathering?

Back

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