1. ROCK TYPES & NAMES
Igneous
Metamorphic
Sedimentary

2. Igneous Rocks Extrusive Intrusive
Igneous rock is formed by magma (molten rock) cooling and becoming solid.
Extrusive
Intrusive

3. Metamorphic Foliated Non Foliated
Metamorphic rock is the result of the transformation of any existing rock type, the protolith, in a process called metamorphism which means "change in form". The protolith is subjected to heat and pressure causing profound physical and/or chemical change.
Foliated
Non Foliated

4. Sedimentary Physically weathered Chemically weathered
Sedimentary rock is a type of rock that is formed by sedimentation of material at the Earth's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral and/or organic particles to settle and accumulate or minerals to precipitate from a solution.
Physically weathered
Chemically weathered

5. Igneous EXTRUSIVE
Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground, Through PYROCLASTIC (explosive) activity or FLOW.
Note: typically pyroclastics occur in felsic volcanism, Flow occurs in mafic volcanoes.
scoria
Pumice
Obsidian
Welded Tuff
Basalt

6. Igneous INTRUSIVE
Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks.
Note: rough crystalline texture!
Gabbro (Mafic-Dark)
GRANITE (Felsic- light)
Dirotie- felsic/mafic

9. Metamorphic FOLIATED

Schist

10. Metamorphic NONFOLIATED
