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 bottom of oceans, rivers, or lakes.

Front

How does weathering affect rocks?

Back

Weathering causes rocks to break down into smaller particles, which can lead to soil formation.

Front

What role does water play in erosion?

Back

Water can erode land by flowing over it, carrying away soil and rock particles, especially during floods.

Front

Can you 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

What is an example of erosion caused by wind?

Back

An example of wind erosion is when strong winds blow sand across a desert, shaping the landscape.

Front

What happens during deposition at a river delta?

Back

During deposition at a river delta, sediments carried by the river are dropped as the water slows down, creating new landforms.

Front

How does ice contribute to weathering?

Back

Ice contributes to weathering through freeze-thaw cycles, where water seeps into cracks, freezes, expands, and eventually breaks the rock apart.

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.
