Physical and Chemical Weathering review

Front

What is Acid Precipitation?

Back

Acid precipitation occurs when strong acids fall to Earth as rain, sleet, or snow, often resulting from pollution.

What is physical weathering?

Back

Physical weathering is the process by which rock is broken down into smaller pieces by physical changes, such as temperature changes or freeze-thaw cycles.

Front

What is weathering?

Back

Weathering is the breakdown of rock material by physical and chemical processes.

Front

True or False: Acids can break down rocks.

Back

False. Acids can indeed break down rocks through chemical weathering.

Front

What is another term for mechanical weathering?

Back

Physical weathering is another term for mechanical weathering.

Front

What is chemical weathering?

Back

Chemical weathering is the process that involves the chemical alteration of minerals in rocks, often due to reactions with water, acids, or gases.

Front

What are the two main types of weathering?

Back

The two main types of weathering are physical weathering and chemical weathering.

Front

Give an example of physical weathering.

Back

An example of physical weathering is the cracking of rocks due to freeze-thaw cycles.

Front

What role does water play in weathering?

Back

Water can cause both physical and chemical weathering; it can freeze in cracks of rocks, causing them to break apart, and it can also dissolve minerals.

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.
