| igneous | rocks formed when lava/magma cools and hardens |
| rock | a hard substance composed of one or more minerals and sometimes organic material |
| sedimentary | rocks formed from particles that have been carried along, deposited, and then compacted and cemeted together |
| metamorhpic | rocks formed heat and pressure change existing rocks into new kinds of rocks |
| intrusive | igneous rock formed from magma cooling and hardening on the inside of 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 |
| compaction | the process when sediment is PUSHED DOWN in layers |
| cementation | the process when sediment CRYSTALLIZES and GLUES itself 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 |
| non-foliated | metamorphic rock that is arranged randomly; no stripes |
