Metamorphic Rocks

Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. Igneous rocks form when rocks are heated to the melting point which forms magma.Sedimentary rocks are formed from the cementing together of sediments, or from the compaction (squeezing together) of sediments, or from the recrystallization of new mineral grains which are larger than the original crystals.

Contact metamorphism. This occurs when an existing rock is exposed to high temperature. When magma intrudes into surrounding rock, the heat from the magma changes the rock that it comes in contact with. Often there is a change in the mineral composition of the original rock and the crystal size increases. The metamorphic rocks also become very ...
