Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals 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 dropping off of sediments in a new place after being transported by erosion.

Front

What type of rock is most likely to form caves through chemical weathering?

Back

Limestone is the type of rock that is most likely to form caves through chemical weathering.

Front

What is the role of carbonic acid in weathering?

Back

Carbonic acid can dissolve limestone over millions of years, leading to the formation of caves and caverns.

Front

What natural forces can cause erosion?

Back

Natural forces that can cause erosion include wind, water (such as rivers and waves), and ice (such as glaciers).

Front

How do waves contribute to erosion?

Back

Waves can erode beaches and lakes by constantly crashing against the shore, removing sand and sediment.

Front

What is the difference between weathering and erosion?

Back

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

Front

What is physical weathering?

Back

Physical weathering is the process of breaking rocks into smaller pieces without changing their chemical composition, often due to temperature changes or freeze-thaw cycles.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often leading to the formation of new minerals and soluble substances.
