- Igneous rocks are formed from the solidification of molten rock material.
- They can be formed inside or outside of the Earth
- Intrusive igneous rocks such as diorite, gabbro, granite that solidify below Earth's surface.
- Extrusive igneous rocks such as basalt, obsidian, pumice, rhyolite and scoria that solidify on or above Earth's surface.
- Sedimentary Rocks are types of rock that are formed by the deposition of material at the Earth's surface and within bodies of water
- They are formed in bodies of water or in places with high wind
- They are formed when any type of rock goes under heat and pressure
- Formed Deep in the Earth
- Foliated and non-Foliated
- Foliated-foliated metamorphic rocks are formed within the earths interior under extremely high pressures that are unequal.
- Non-foliated-Non foliated metamorphic rock are formed around igneous rock where the temperatures are high but the pressures are low and equal
The rock cycle is a cycle that shows how rocks are formed,where they are formed,and their minerals and crystal size and description, there are three main types Sedimentary,Metamorphic, and igneous
