What is the difference between extrusive and intrusive igneous rocks?

Back

Extrusive igneous rocks form from lava that cools quickly on the Earth's surface, while intrusive igneous rocks form from magma that cools slowly beneath the surface.

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 forming solid rock.
