5 Formation
5.1 Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
