Extrusive Rocks |
When volcanic material erupts and cools and crystallizes on Earth's surface. Type of Igneous rock. |
|
|
Volcanic glass |
The rocks that form when lava cools too quickly to form crystals. |
|
|
Intrusive rock |
A type of igneous rock that forms as magma cools underground. |
|
|
Compaction |
The weight from the layers of sediment forces out fluids and decreases the space between grains. |
|
|
Clastic |
Sedimentary rocks that are made up of clasts. |
|
|
Clasts |
The fragments and broken pieces of minerals that make up clastic rocks. |
|
|
Chemical rocks |
Form when minerals crystallize directly from water. |
|
|
Biochemical rocks |
A sedimentary rock that was formed by organisms or contains the remains of organisms. |
|
|
Metamorphism |
Any process that affects the structure or composition of a rock in a solid state as a result of changes in temperature, pressure, or the addition of chemical fluids. |
|
|
Plastic Deformation |
The permanent change in shape by bending and folding. |
|
|
Contact Metamorphism |
Magma comes in contact with existing rock, and it's thermal energy and gases interact with the surrounding rock, forming new metamorphic rocks. |
|
|
Regional Metamorphism |
The formation of metamorphic rock bodies that are hundreds of square kilometers in size. |
|
|
Cementation |
When minerals dissolve in water crystallize between sediment grains. |
|
|
Foliated Rock |
Rocks that contain parallel layers of flat and elongated minerals. |
|
|
Non-Foliated rock |
Metamorphic rocks that have mineral grains with a random, interlocking texture. |
