Explanation:

There are three kinds of rock: igneous, sedimentary, and metamorphic.

Igneous Rock

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. ... Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet Ex - Devil's Tower Rock

Sedimentary Rock

Sedimentary Rock Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.Ex - Sandstone and Siltstone ।

Metamorphic Rock

Metamorphic rocks are formed when igneous rock or sedimentary rock are changed by great heat and/or pressure. ... Here magma came in contact with the surrounding sandstone rock as the magma upwelled into a fold mountain. The heat from this magma body within the fold mountain changed the sandstone to quartzite.

Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble. Foliated Metamorphic Rocks: Some kinds of metamorphic rocks -- granite gneiss and biotite schist are two examples -- are strongly banded or foliated.
