Processes of Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process that breaks rocks down into smaller pieces.

Front

What is erosion?

Back

Erosion is the process that moves pieces of rock by wind, water, and ice.

Front

What transforms sedimentary rock into metamorphic rock?

Back

Heat and pressure are used to change sedimentary rock into metamorphic rock.

Front

What type of rock is formed by heat and pressure?

Back

Metamorphic rock is formed from the process of heat and pressure.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down in new locations after being transported by erosion.

Front

What are the main agents of erosion?

Back

The main agents of erosion are wind, water, and ice.

Front

How does weathering differ from erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion moves those pieces away.

Front

What role does water play in weathering?

Back

Water can cause weathering through processes like freeze-thaw cycles and chemical reactions.

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.
