|---|
| igneous | rocks formed when lava/magma cools and hardens |
| sedimentary | rocks from sediment deposited in layers over millions of years |
| metamorhpic | rocks formed heat and pressure deep inside the earth (made from previously existing rock) |
| intrusive | igneous rock formed from magma cooling and hardening inside Earth |
| extrusive | igneous rock formed from lava cooling and hardening on the surface of Earth |
| erosion | the process when sediment is CARRIED |
| deposition | the process when sediment is DROPPED (settles of natural forces carrying it) |
| compaction | the process when sediment is PUSHED DOWN in layers |
| cementation | the process when minerals CRYSTALLIZE and GLUE sediments together |
| clastic | sedimentary rock formed when many fragments of different rocks push together to make a new rock |
| organic | sedimentary rock made when the remains of LIVING things are compacted and cemented together |
| chemical | sedimentary rock formed when water evaporates and the remaining sediment crystalizes |
| sediment | small solid pieces of rock and organic material |
| foliated | metamorphic rock that is lined up in a banded pattern (stripes) |
| non-foliated | metamorphic rock that is arranged randomly (no stripes) |
| weathering | the process when rock and organic material is BROKEN DOWN by natural forces into sediment |
