Weathering and Erosion, Deposition True or False

True or False: Weathering always happens slowly, over many thousands of years.

• True

• False

True or False: Weathering and erosion are different names for the same process.

• True

• False

The two types of weathering are

• terrestrial and aquatic.

• wind and precipitation.

• mechanical and chemical.

• physical and metaphysical.

Which of these is an example of weathering?

• a landslide moving debris down the side of a mountain

• a large rock cracking into many smaller pieces around a tree root

• wind blowing sand from one side of a beach to the other

• glaciers slowly carrying bits of rock along the ground

Mechanical weathering is also called ________ weathering.

• physical

• chemical

• glacial

• sedimentary

Mechanical weathering does not change a rock’s

• shape.

• size.

• appearance.

• composition.

Which of these is most likely to cause chemical weathering?

• abrasion from sediment

• frost wedging

• acid rain

• large plant roots

Which of these best describes erosion?

• the natural wearing down of rock into smaller pieces due to abrasion

• the movement of rock and sediment due to wind, water and other forces

• the chemical composition of a type of rock

• the natural features of the Earth’s surface, such as mountains and canyons

Which of these is the best example of deposition?

• Acid rain changes the chemical composition of limestone.

• Flowing water wears away the sharp edges of river rocks.

• A glacier melts and drops the sediment it was carrying.

• Water seeps into cracks in a rock, freezes and melts.

Landslides are an example of

• weathering.

• erosion.

• deposition.

• chemical change.
