Weathering, Erosion & Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the movement of soil and rock from one place to another by natural forces like wind, water, ice, and gravity.

Front

What is deposition?

Back

Deposition occurs when eroded materials stop moving and begin to build up in a new location.

Front

How do plants contribute to weathering?

Back

Plants weather rocks by growing roots into cracks, which can expand and break the rock apart.

Front

What natural force is largely responsible for the formation of the Grand Canyon?

Back

Water is largely responsible for the formation of the Grand Canyon through erosion.

Front

What is the role of gravity in erosion?

Back

Gravity pulls soil and rock down slopes, contributing to erosion.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breaking down of rocks without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to water and acids.

Front

Give an example of erosion caused by water.

Back

Rivers can erode the land by carrying away soil and rock as they flow.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces to new locations.
