Rocks and the Rock Cycle

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

Igneous, Sedimentary, and Metamorphic.

Front

How do sedimentary rocks form?

Back

Sedimentary rocks form through the compaction and cementation of sediments.

Front

What is metamorphism?

Back

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

Front

What is the difference between magma and lava?

Back

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

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which weathered rock and soil are moved from one location to another, often by water, wind, or ice.

Front

What is compaction in the context of sedimentary rocks?

Back

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

Front

What is cementation?

Back

Cementation is the process where dissolved minerals precipitate from water and fill the spaces between sediments, binding them together to form rock.

Front

What are igneous rocks?

Back

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