Rock Cycle

What is the Rock Cycle?

Back

The Rock Cycle is the process that makes and recycles rocks, involving the formation, breakdown, and reformation of rocks through various geological processes.

Front

What are the three major classes of rocks?

Back

The three major classes of rocks are Igneous, Metamorphic, and Sedimentary.

Front

How is Igneous rock formed?

Back

Igneous rock is formed when lava cools and hardens.

Front

What process transforms granite into gneiss?

Back

Granite transforms into gneiss through the process of heat and pressure.

Front

What characteristic is commonly found in Sedimentary rocks?

Back

Fossils are commonly found in Sedimentary rocks.

Front

What is the main difference between Igneous and Sedimentary rocks?

Back

Igneous rocks are formed from cooled lava or magma, while Sedimentary rocks are formed from the accumulation of sediments.

Front

What is metamorphism?

Back

Metamorphism is the process by which existing rocks are changed into metamorphic rocks due to heat, pressure, or chemically active fluids.

Front

What is the role of weathering in the Rock Cycle?

Back

Weathering breaks down rocks into smaller particles, which can then be transported and deposited to form Sedimentary rocks.

Front

What is the process of lithification?

Back

Lithification is the process of compacting and cementing sediments to form Sedimentary rocks.

Front

What is magma?

Back

Magma is molten rock located beneath the Earth's surface, which can cool to form Igneous rocks.
