Rock Cycle Review

Front

What is the rock cycle?

Back

The rock cycle is a continuous process where rocks change from one type to another through various geological processes such as melting, cooling, erosion, and compaction.

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 molten rock (magma or lava).

Front

What process turns sediment into sedimentary rock?

Back

Compaction and cementation turn sediment into sedimentary rock.

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 pieces, which can then be transported and deposited to form sedimentary rocks.

Front

What is the difference between magma and lava?

Back

Magma is molten rock beneath the Earth's surface, while lava is molten rock that has erupted onto the Earth's surface.

Front

What is the process of melting in the rock cycle?

Back

Melting occurs when rocks are subjected to high temperatures, causing them to turn into magma.

Front

What are fossils, and how do they relate to sedimentary rocks?

Back

Fossils are the preserved remains of ancient organisms found in sedimentary rocks, formed from sediments that compacted and cemented over time.

Front

What is the significance of heat and pressure in the formation of metamorphic rocks?

Back

Heat and pressure cause changes in the mineral composition and structure of existing rocks, transforming them into metamorphic rocks.
