It involves the recrystallization of minerals in rocks as a result of pressure and temperature changes

• Sedimentary Rock

• Igneous Rock

• Metamorphic Rock

• Weathering of rocks

It occurs under conditions of HIGH temperature and HIGH pressure.

• Contact Metamorphism

• Regional Metamorphism

• Non foliated

• Foliated Rock

It formed when mineral grains line up in parallel layers.

• Contact Metamorphism

• Regional Metamorphism

• Non foliated

• Foliated Rock

All are type of metamorphic rock EXCEPT:

• Phyllite

• Slate

• Sandstone

• Gneiss

It form when hot, molten rock crystallizes and solidifies.

It formed on the surface of the Earth from lava, which is magma that has emerged from underground.

• Solidification

• Extrusive Rock

• Intrusive Rock

• Crystallization

They have a high silica concentration, ranging from 53 to 65 percent SiO2.

• Ultramafic Igneous Rocks

• Mafic Igneous Rocks

• Intermediate Igneous Rocks

• CrystallizationFelsic Igneous Rocks

They contain extremely little silica, less than 45 percent SiO2. Its magma has a low viscosity before creating igneous rocks.

• Ultramafic Igneous Rocks

• Mafic Igneous Rocks

• Intermediate Igneous Rocks

• CrystallizationFelsic Igneous Rocks

An igneous type of rocks that do have obvious minerals based on their texture.

• Aphanitic (fine-grained) texture

• Vesicular texture

• Pegmatitic texture

• Glassy texture
