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 by natural forces such as wind or water.

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 deltas.

Front

How does freezing water cause weathering?

Back

When water seeps into cracks in rocks and freezes, it expands, causing the cracks to widen and eventually break the rock apart.

Front

What role do strong winds play in erosion?

Back

Strong winds can carry small pieces of rock and soil away from one location, contributing to the erosion of landscapes.

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, created by the deposition of sediment.

Front

What is acid rain and how does it affect rocks?

Back

Acid rain is rain that has been made acidic by pollutants. It can cause weathering by creating holes and wearing down rocks and statues.

Front

What happens to sand on a beach during deposition?

Back

During deposition, waves can carry sand and drop it onto the beach, piling it up in new locations.

Front

What is the difference between weathering and erosion?

Back

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

Front

Can plants contribute to weathering?

Back

Yes, plant roots can grow into cracks in rocks, causing them to break apart, which is a form of biological weathering.
