What is the type of rock?

Answer 1

There are three main types of rocks found on earth and they are;

Igneous: are intrusive rocks that have come up from with the mantle or the earths crust. For instance a granite is an intrusive or extrusive rock that was either erupted (extrusive) from a volcano or but brought up in a magma chamber (intrusive), whilst a basalt is a lava flow and is volcanic.

Sedimentary: is rock made from sediment being deposited over millions of years and then hardened under pressure, temperature and diagenesis. A sandstone or a mudstone are the best examples of sedimentary rocks. Sedimentary rocks are divided in to two different groups siliciclastic rocks and carbonate rocks.

Metamorphic: are any of the two previous rock types that have had either there physical or chemical structure changed due to pressure or temperature. An example of this is for sedimentary rock a sandstone is metamorphosed into a quartzite and for igneous rocks a granite is metamorphosed into a gneiss.

Answer 2

There are three main types of rocks: Igneous rocks, formed from the solidification of molten material; sedimentary rocks, formed from the deposition and lithification of sediments; and metamorphic rocks, formed from the alteration of pre-existing rocks due to heat and pressure.
