• True

• false

True

Flowing water can create valleys.

Multiple Choice

Very large boulders do not breakdown over time; only smaller ones do.

• True

• False

False

Multiple Choice

Which is most like a glacier changing earth's surface?

• a bird drinking water from a puddle

Multiple Choice

Which of the following does not cause a quick change to the Earth's surface?

• earthquake

• erosion

• avalanche

• landslide

Erosion

Erosion is the weathering and removal of rocks and soil. This occurs over a long period of time.

Multiple Choice

Gravity pulls rainwater downhill and the flowing water erodes the landscape by

• forming sand dunes

• washing away soil

• forming a desert

• forming moraines

Gravity pulls rainwater downhill and the flowing water erodes the landscape by washing away soil.

Multiple Choice

The weathered rocks found along the side of a stream were likely place there by

• deposition

• transport

• erosion

• weathering

deposition

The weathered rocks found along the side of a stream were likely placed there by deposition. Deposition is the dropping off of eroded soil and bits of rock.

Multiple Choice

What happens during physical weathering?

• It snows.

• Rocks are chemically changed into limestone.

• The size and the shape of rocks are changed.

• Rust is created from the combination of water and air.

The size and the shape of rocks are changed during physical weathering.
