Unit 4 Review

Front

What is plate tectonics?

Back

The theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

How do tectonic plates create new rock?

Back

The movement of tectonic plates can cause magma to rise from the mantle, which cools and solidifies to form new rock.

Front

What is erosion?

Back

The process of transporting rock fragments by water, wind, ice, or gravity.

Front

What is compaction in geology?

Back

The process where layers of sediment build up and exert pressure on the layers below, causing them to become denser.

Front

What is sediment?

Back

Small fragments of rock and minerals that have been broken down by weathering and erosion.

Front

What is the rock cycle?

Back

The continuous process of rock formation and transformation, including the processes of igneous, sedimentary, and metamorphic rock formation.

Front

What is lithification?

Back

The process of turning sediment into solid rock through compaction and cementation.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces.

Front

What type of rock is formed from cooled magma?

Back

Igneous rock.

Front

What is metamorphic rock?

Back

Rock that has been changed from its original form due to heat and pressure.
