1 Relationships among the major rock groups
The Rock Cycle Relationships among the major rock groups

2 Major Rock Groups Igneous Formed from molten rock
Plutonic (intrusive):slow cooling and crystallization deep w/in Earth’s crust Volcanic (extrusion): quick cooling at the surface Sedimentary Formed at the Earth’s surface Clastic (Mineral Fragments or grains, clays) Chemical (crystalline chemical/biochemical precipitate Organic (remains of past organisms, typically shell-bearing) Metamorphic Changed by pressure, temperature and fluids. Foliated visible bands Nonfoliated no banding pattern

14 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”.
