1. Rocks and The Rock Cycle

2. 3 Main Rock Types
Igneous
Sedimentary
Metamorphic

3. 3 Main Rock Types
Igneous
Sedimentary
Metamorphic

4. Igneous EXTRUSIVE Forms when lava cools quickly on the Earths surface
Forms from molten rock cooling and solidifying
INTRUSIVE
Magma cools slowly over millions of years deep beneath the surface

5. Igneous EXTRUSIVE Forms when lava cools quickly on the Earths surface
Forms from molten rock cooling and solidifying
INTRUSIVE
Magma cools slowly over millions of years deep beneath the surface

6. IGNEOUS---Extrusive Little or NO Crystals!
Lava cools on the surface so fast mineral do not get a chance to form
Extrusive rocks can be divided into two categories based on color
Dark colors black-brown-red
Basalt
Obsidian
Light colors white-gray-pink
Rhyolite

10. Igneous EXTRUSIVE Forms when lava cools quickly on the Earths surface
Forms from molten rock cooling and solidifying
INTRUSIVE
Magma cools slowly over millions of years deep beneath the surface

11. IGNEOUS---Intrusive Large Interlocking Crystals!!!
Magma cools slowly over millions of years…
LARGE CRYSTALS FORM
Intrusive rocks can also be divided into two categories based on color
Dark colors black-brown-green
Gabbro
Light colors white-gray-pink
Granite

15. 3 Main Rock Types
Igneous
Sedimentary
Metamorphic

16. How to make a clastic sedimentary rock
Weathering and Erosion
Transportation
Deposition
Compaction and Cementation
Sedimentary Rock

17. Sedimentary Chemical Clastic Shale Sandstone Conglomerate
Sedimentary rocks are divided into two categories
Chemical
Mineral are dissolved in to the water…water is evaporated off and leaves behind chemical sedimentary rocks
Examples are Halite, Limestone and Gypsum
Clastic
Made from eroded fragments of other rocks
Shale
Microscope grains of mud cemented together
Sandstone
Sand grains cemented together
Conglomerate
Pebble to boulder size fragments cemented together

19. 3 Main Rock Types
Igneous
Sedimentary
Metamorphic

20. Metamorphic rocks form from HEAT&PRESSURE
Two types of metamorphism
Contact
Rock surrounding a magma body get cooked and changes due
Regional
Tectonic forces
Metamorphism occurs over a large area

21. Contact Metamorphism
Deep underground, zones of metamorphism form around the hot magma of batholiths.
L.Gardiner/Windows Original

22. Regional Metamorphism
Tectonic forces smash continents together. The rocks get heated and become semi-molten. The added pressure causes the mineral to separate into bands and sometime to even flow before cooling again!

23. How are Metamorphic rocks formed?

24. Common Metamorphic Rocks
Parent Rock
Metamorphic Rock
Granite
Gneiss
Shale
Slate
Sandstone
Quartzite

25. Foliated - vs. - Non Foliated
Foliated: These types of metamorphic rock are distinctly layered.
This is due to the immense directional pressure that the rock is exposed to.

26. Foliated Examples

27. Foliated - vs. - Non-Foliated
As opposed to the foliated metamorphic rocks, the non-foliated rocks are not distinctly layered.   
This is probably because non-foliated rocks were exposed to high temperature conditions, but not to high directional pressure conditions.  

28. Non – Foliated Examples
Marble from Limestone
Quartzite from Sandstone
