Weathering and Rock Processes Drills

A student finds a rock that has broken into smaller pieces without changing its chemical composition. Which process most likely caused this?

• Chemical weathering

• Mechanical weathering

• Deposition

• Cementation

Which scenario BEST represents chemical weathering?

• Tree roots breaking apart a sidewalk

• Waves crashing and breaking down cliffs

• Limestone dissolving due to acid rain

• Rocks cracking from freezing water

Frost wedging occurs when—

• animals burrow into the ground

• water freezes and expands in cracks repeatedly

• glaciers scrape rocks along the ground

Exfoliation most often happens because—

• plant acids dissolve minerals

• pressure is released from overlying rock layers

• water carries sediments downhill

• animals dig holes in the soil

A student observes moss growing on a rock and notices the rock surface weakening. What process is occurring?

• Abrasion

• Deposition

• Biological weathering

• Cementation

Which of the following is BEST described as the movement of sediments from one place to another?

• Weathering

• Erosion

• Deposition

• Compaction

Sediments carried by a river begin to settle at the mouth of the river. What process is this?

• Abrasion

• Erosion

• Weathering

• Deposition
