Front

What is an example of mass-wasting?

Back

Mudflow is an example of mass-wasting.

Front

Back

A rock that resists weathering would have a quartz-rich look.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those weathered materials.

Front

What is mass-wasting?

Back

Mass-wasting is the downward movement of soil and rock due to gravity.

Front

What role does vegetation play in erosion?

Back

Vegetation helps to minimize erosion by stabilizing the soil.

Front

What is the primary agent of erosion in deserts?

Back

Wind is the primary agent of erosion in deserts.

Front

What is a shield volcano?

Back

A shield volcano is a broad, domed volcano with gently sloping sides, formed by the eruption of low-viscosity lava.
