Weathering, Erosion, Deposition Flashcard

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 materials carried by wind, water, or ice are dropped in a new location, forming new landforms.

Front

Example of Weathering:

Back

Water getting into cracks, freezing, and breaking the rocks apart.

Front

Example of Erosion:

Back

Flood waters moving soil from one location to another.

Front

Example of Deposition:

Back

Waves dropping sand on the beach.

Front

What causes Weathering?

Back

Weathering can be caused by temperature changes, water, ice, and biological activity.

Front

What are the types of Weathering?

Back

There are two main types of weathering: mechanical (physical) weathering and chemical weathering.

Front

What is Mechanical Weathering?

Back

Mechanical weathering is the physical breakdown 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 reactions with water or acids.
