Its time to ROCK and roll! :D

Igneous rock A type of rock that is formed when magma cools and hardens
Most igneous rocks are crystalline
Magma Molten rock BELOW the surface
Lava Molten rock ABOVE the surface
Crystalline Full of crystals
Extrusive Rocks formed on the surface
Intrusive Rocks formed below the surface; larger crystals
Coarse- grained Rocks with large mineral grains such as Granite.
Fine- grained Rocks with small mineral grain such as rhyolite
Glassy Rock glass formed from molten rock, Ex: Obsidien
Vesicular Igneous rock with lots of holes formed from bubbling gas
Felsic Forms from magma with high concentration of silica. (Ex. granite)
Mafic Forms from magma with high concentration of iron and magnesium (Ex. basalt)
Porphyritic Rock with a mix of large and small crystals; granite is an example
Compaction the process where sediments are squeezed together which makes the pore space shrink
Cementation When sediments are glued together by minerals deposited by water
Chemical Sedimentary Rock form when ions from dissolved minerals precipitate because of changing in the concentration of chemicals
Physical Sedimentary Rock Rocks that form from the remnants of living things. Ex. coal or limestone
Clastic sedimentary rock When rock fragments carried by the elements cement together to form rocks
Sorting The tendency of water and air able to flow through the rock
Angularity How jagged the rock fragments are in a sedimentary rock
Stratification Layers of sedimentary rock
Cross-bedding rocks in slanted layers
Ripple marks Caused by the elements
Mud cracks When muddy deposits shrink and make cracks
