Weathering and Erosion

This type of weathering in which rock is physically broken into smaller pieces.

• Chemical weathering

• Erosion

• Mechanical weathering

• Deposition

What do we call the process in which rock is broken down by changes in its chemical makeup.

• Chemical weathering

• Mechanical weathering

• Erosion

• Deposition

The grinding/scratching away of rock by other rock particles carried in water, ice, or wind

• Frost wedging

• Exfoliation

• Oxidation

• Abrasion

A type of chemical weathering in which a substance combines with oxygen, as when iron oxidizes, forming rust.

• Acid rain

• Oxidation

• Reaction to water

• Exfoliation

A student prepares a model by filling a plastic bottle with water, capping it tightly, and placing it in the freezer for 24 hours. After 24 hours, there are large cracks on the bottle's sides. The student's model most likely represents which of the following types of weathering:

• Acid rain

• Oxidation

• Frost wedging

• Abrasion

Plants/animals digging under ground with roots or claws to break apart rocks.

• Frost wedging

• Abrasion

• Burrowing

• Exfoliation

Which event breaks rocks down into smaller pieces?

• Sedimentation

• Deposition

• Weathering

• Erosion

In what way are weathering and erosion the same?

• Both move sediment from one place to another.

• Both break down rocks into smaller pieces

• Both change the Earth's surface

• Both leave sediment in new places
