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

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 is the difference between physical and chemical weathering?

Back

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

Front

What is an example of chemical weathering?

Back

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

Front

What is an observational study?

Back

Classifying animals based on their characteristics.

Front

What is sedimentation?

Back

The process by which sediment settles out of the water or wind carrying it.

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by wind or water flow.

Front

What is the role of compaction in the rock cycle?

Back

Compaction is the process that compresses sediments together to form sedimentary rock.

Front

What is the definition of metamorphic rock?

Back

Rocks that have been changed from their original form by heat, pressure, or chemically.

Front

What is the main cause of physical weathering?

Back

Physical weathering is mainly caused by temperature changes, freeze-thaw cycles, and mechanical forces.
