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 below Earth’s surface –Volcanic (extrusive)- fast cooling above Earth’s suface Granite

3. 3 Major Rock Groups Sedimentary –Formed at the Earth’s surface –Sediments are compacted together by pressure BrecciaChertSandstone

4. 4 Major Rock Groups Metamorphic –Rock that is changed due to heat & pressure Geniss MarblePhyllite

16. 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”. In Conclusion…
