Rock Cycle and Types of Rocks Flashcard

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes how rocks change from one type to another over time through various geological processes.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How do igneous rocks form?

Back

Igneous rocks form from the cooling and solidification of magma or lava.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces by natural forces such as wind, water, and ice.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another by natural forces.

Front

What processes lead to the formation of sedimentary rocks?

Back

Sedimentary rocks are formed through weathering, erosion, deposition, compaction, and cementation.

Front

What is metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed into metamorphic rocks due to extreme heat and pressure.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What is compaction in the context of sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume and helping to form sedimentary rocks.

Front

What is cementation?

Back

Cementation is the process where dissolved minerals crystallize and bind sediment particles together to form sedimentary rocks.
