Exploring 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 processes like 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 are igneous rocks formed?

Back

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

Front

What is sedimentation?

Back

Sedimentation is the process by which sediments settle out of a fluid, often leading to the formation of sedimentary rocks.

Front

What is compaction in the context of sedimentary rock formation?

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 crystallize and bind sediment particles together, forming solid rock.

Front

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.

Front

What is weathering?

Back

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

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another by natural forces like water, wind, or ice.

Front

What are fossils?

Back

Fossils are the preserved remains or traces of ancient organisms, often found in sedimentary rocks.
