Types of rocks
Geologists define a rock any coherent, naturally occurring substance generally composed of minerals. Rocks are grouped into three categories that are igneous rocks, Sedimentary rocks, and metamorphic rocks.
Igneous rocks are formed by the solidification of magma, a silicate liquid generated by partial melting of the upper mantle or the lower crust. Different environments of formation, and the cooling rates associated with these, create very different textures. There are two main groupings of igneous rocks: volcanic rocks and plutonic rocks.
Volcanic rocks form when magma rises to the surface and erupts, either as lava or pyroclastic material. The rate of cooling of the magma is rapid, and crystal growth is inhibited. Volcanic rocks are characteristically fine-grained. Volcanic rocks at times show structures from their eruption, e.g. molded by shearing the lava as it flowing or banding flow, and exposed voids or cracks that signify bolted gases. Plutonic rocks on the other hand develop when magma cools inside the Earth's crust. The degree at which magma cools is slow thus it allows growing of large crystals. Plutonic rocks are typically coarse-grained. Igneous rocks play a significant role in geology in the following:
