Typically, the melting of rocks is caused by one or more of three processes namely; an increase in temperature, a decrease in pressure, or a change in composition.

    Sedimentary rocks form when small particles of rock and mineral combine into one rock. There are two primary types of sedimentary rock clastic and chemical. Clastic sedimentary rocks, like sandstone and shale, are composed of grains of rocks and minerals that have been chemically or mechanically broken off from preexisting rocks.

When volcanoes erupt and when mountains are formed by the movement of Earths tectonic plates, rocks are heated and squeezed. The minerals in the rocks are then changed, forming metamorphic rocks.

    Metamorphic rocks are formed through the transformation of preexisting rocks in a process known as metamorphism (meaning change in form). The original rock, or protolith, is subjected to heat and pressure which cause physical, chemical and mineralogical changes to the rock.Protoliths may be igneous, sedimentary or preexisting metamorphic rocks.
