Weathering, Erosion & Deposition Identification

Front

What is weathering?

Back

Weathering is the process by which rocks are broken down into smaller pieces due to various factors such as wind, water, and temperature changes.

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 are sediments?

Back

Sediments are small pieces of broken rocks and minerals that are carried away by erosion and can accumulate in new locations.

Front

What is deposition?

Back

Deposition is the process by which sediments are laid down or settled in a new location after being transported by erosion.

Front

How does weathering differ from erosion?

Back

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

Front

What role does water play in weathering?

Back

Water can cause weathering through processes like freeze-thaw cycles, where water seeps into cracks, freezes, expands, and breaks the rock apart.

Front

Can plants contribute to weathering?

Back

Yes, plant roots can grow into cracks in rocks, and as they grow, they can break the rocks apart, contributing to weathering.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often through reactions with water and other substances.

Front

Give an example of erosion caused by wind.

Back

An example of wind erosion is the formation of sand dunes in deserts, where wind carries away loose sand and deposits it in new areas.
