Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

Erosion is 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

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often occurring at the mouth of rivers or in lakes.

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 different location.

Front

What is an example of erosion?

Back

An example of erosion is a mudslide flowing down a steep hill.

Front

What is an example of deposition?

Back

An example of deposition is the formation of deltas at the mouths of rivers.

Front

How do waves contribute to deposition?

Back

Waves can drop sand on the beach, which is a form of deposition.

Front

What role does wind play in weathering?

Back

Wind can blast sand at rocks, causing them to wear away and form shapes like arches.

Front

What happens to ponds over time due to deposition?

Back

Ponds can fill up with sediment and eventually become marshes due to deposition.

Front

What is physical weathering?

Back

Physical weathering is the breaking down of rocks without changing their chemical composition, often through processes like freeze-thaw cycles.
