Rock Cycle

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various geological processes, including igneous, sedimentary, and metamorphic formations.

Front

What processes can change a metamorphic rock?

Back

Higher temperature and pressure can change a metamorphic rock without altering its classification.

Front

How do temperature and pressure change with depth in the geosphere?

Back

Both temperature and pressure increase as depth in the geosphere increases.

Front

In which type of rock are fossils commonly found?

Back

Fossils are commonly found in sedimentary rocks, as they are formed from the remains of once living things.

Front

What can be inferred about a rock with large, light-colored mineral crystals that shows no signs of alteration?

Back

It can be inferred that the rock formed from hardened magma below Earth’s surface.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through physical, chemical, or biological means.

Front

What is the difference between igneous and sedimentary rocks?

Back

Igneous rocks form from cooled magma or lava, while sedimentary rocks form from the accumulation and compaction of mineral and organic particles.

Front

What is metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed into metamorphic rocks due to changes in temperature, pressure, or the presence of chemically active fluids.

Front

What is lithification?

Back

Lithification is the process of turning sediments into solid rock through compaction and cementation.

Front

What role does erosion play in the rock cycle?

Back

Erosion is the process that removes weathered rock and soil, transporting them to new locations where they can accumulate and form sedimentary rocks.
