Weathering, Erosion, & Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces such as 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 at the end of a river or in a delta.

Front

How do plant roots contribute to weathering?

Back

Plant roots can grow into cracks in rocks, exerting pressure and causing the rocks to split apart, which is a form of weathering.

Front

What role does water play in erosion?

Back

Water can carry away soil and rocks, especially in fast-moving rivers, leading to erosion of the landscape.

Front

What is an example of deposition?

Back

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

Front

Is deposition the same as erosion?

Back

No, deposition is the process of dropping off sediments, while erosion is the process of removing and transporting sediments.

Front

What is the effect of waves on beaches?

Back

Waves can erode the shoreline and deposit sand on the beach, contributing to the formation of coastal landforms.

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, often leading to their dissolution or formation of new minerals.
