Rocks and The 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 are igneous rocks?

Back

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

What is the difference between lava and magma?

Back

Lava is molten rock that is found above the Earth's surface, while magma is molten rock located below the Earth's surface.

Front

What processes occur during the formation of sedimentary rocks?

Back

Sedimentary rocks are formed through weathering, erosion, deposition, compaction, and cementation of sediments.

Front

What is weathering?

Back

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

What is erosion?

Back

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

What is deposition?

Back

Deposition is the process where sediments settle out of a transporting medium (like water or wind) and accumulate in a new location.

Front

What is compaction?

Back

Compaction is the process by which sediments are pressed together under pressure, reducing their volume.

Front

What is cementation?

Back

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

Front

What are metamorphic rocks?

Back

Metamorphic rocks are formed from existing rocks that have been changed by heat, pressure, or chemically active fluids.
