What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various stages: igneous, sedimentary, and metamorphic, and how they can change from one type to another over time.

How do igneous rocks form?

Back

Igneous rocks form from the cooling and solidification of molten rock (magma or lava).

What is the primary characteristic of sedimentary rocks?

Back

Sedimentary rocks are primarily characterized by being formed from the accumulation and compaction of mineral and organic particles.

Front

What role do fossils play in sedimentary rocks?

Back

Fossils are often found in sedimentary rocks, as these rocks form in environments where organisms can be buried and preserved.

What is metamorphism?

Back

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

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks into smaller pieces, while erosion is the movement of those pieces from one location to another.

What is the significance of the rock cycle in geology?

Back

The rock cycle is significant in geology as it explains the dynamic processes that shape the Earth's crust and the interrelationships between different rock types.

What is compaction in the context of sedimentary rock formation?

Back

Compaction is the process by which sediments are pressed together under pressure, reducing their volume and leading to the formation of sedimentary rocks.
