3 Major Rock Groups Igneous Sedimentary Metamorphic
Formed from a melt (molten rock) Intrusive):slow cooling and crystallization Extrusion): quick cooling at the surface Sedimentary Formed at the Earth’s surface Clastic (Mineral Fragments or grains, clays) Chemical (crystalline chemical/biochemical precipitates) Metamorphic Changed by pressure, temperature and fluids.

15 In Conclusion… The rock cycle demonstrates the relationships among the three major rock groups It is powered by the interior heat of the Earth As well as earth’s momentum and… The energy from the sun It involves processes on the Earth’s surface as well as the Earth’s interior It connects the “hydrologic cycle” with the “tectonic cycle”.
