Weathering Processes and Effects

Front

What happens to a rock when it weathers?

Back

It breaks into small pieces.

Front

How does the rate of weathering change as a particle of sediment in a stream breaks into smaller pieces?

Back

The rate of weathering increases due to an increase in surface area.

Front

What is abrasion in the context of weathering?

Back

Abrasion is the process by which rocks scrape against one another.

Front

What can weak carbonic acid dissolve limestone to form over millions of years?

Back

Caves and caverns.

Front

What are the two factors that affect the rate at which weathering occurs?

Back

Type of rock and climate.

Front

Define weathering.

Back

Weathering is the process of breaking down rocks into smaller pieces through physical or chemical means.

Front

What is mechanical weathering?

Back

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

Front

Give an example of chemical weathering.

Back

An example of chemical weathering is the reaction of acid rain with limestone.

Front

What role does climate play in weathering?

Back

Climate affects the rate of weathering; warmer and wetter climates typically increase weathering rates.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken pieces by wind, water, or ice.
