23 Rock Transformations

Front

What is rock transformation?

Back

Rock transformation refers to the processes through which rocks change from one type to another, including weathering, erosion, compaction, cementation, melting, and cooling.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How do sedimentary rocks form?

Back

Sedimentary rocks form through the processes of compaction and cementation of sediments over time.

Front

What is weathering?

Back

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

Front

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one location to another, often by water, wind, or ice.

Front

What is the role of the sun in rock transformation?

Back

The sun provides energy that drives weathering processes, helping to break down rocks into sediments.

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 rock.

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

How do igneous rocks form?

Back

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

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.
