1 The Rock Cycle Thinking about relationships among the major rock groups

2 2 Major Rock Groups Igneous –Formed from a melt (molten rock) –Plutonic (intrusive):slow cooling and crystallization –Volcanic (extrusion): quick cooling at the surface Sedimentary –Formed at the Earths surface –Clastic (Mineral Fragments or grains, clays) –Chemical (crystalline chemical/biochemical precipitates) Metamorphic –Changed by pressure, temperature and fluids.

14 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 earths momentum and… The energy from the sun It involves processes on the Earths surface as well as the Earths interior It connects the hydrologic cycle with the tectonic cycle. In Conclusion…
