Unit 5 Review - In-Class

Front

What process transforms sedimentary and igneous rocks into metamorphic rocks?

Back

Extreme heat and pressure chemically change them.

Front

What is the main difference between physical and chemical weathering?

Back

Physical weathering breaks rocks mechanically; chemical weathering alters their chemical composition.

Front

How do weathering, erosion, and deposition contribute to the rock cycle?

Back

Weathering creates sediment and is carried by erosion forming new sedimentary rock.

Front

What natural processes primarily form most beaches?

Back

Erosion and sedimentation.

Front

What is an example of chemical weathering?

Back

The reaction of acid rain with limestone, leading to its dissolution.

Front

What is weathering?

Back

The process of breaking down rocks into smaller pieces through physical or chemical means.

Front

What is erosion?

Back

The movement of sediment from one location to another, often by wind, water, or ice.

Front

What is deposition?

Back

The process by which sediment settles out of the transporting medium and accumulates in a new location.

Front

What role does compaction play in sedimentary rock formation?

Back

Compaction reduces the volume of sediment, squeezing particles together to form solid rock.

Front

What is cementation in the context of sedimentary rocks?

Back

Cementation is the process where dissolved minerals precipitate and bind sediment particles together.
