Rockcycle
The document discusses the rock cycle and the three main types of rocks - igneous, sedimentary, and metamorphic. Igneous rocks form from cooling magma, either slowly underground as plutonic rocks or quickly on the surface as volcanic rocks. Sedimentary rocks form from the lithification of sediments at the earth's surface. Metamorphic rocks form by changes to other rock types through heat, pressure, and fluids in the earth's crust. The rock cycle demonstrates how rocks continuously transform between these three types through geological processes over long periods of time.
Rockcycle
- 1. The Rock Cycle Thinking about relationships among the major rock groups
- 2. 2 Major RockGroups • Igneous – Formed from a melt (molten rock) – Plutonic (intrusive):slow cooling and crystallization – Volcanic (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.

- 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”.
