rock that forms when magma cools | igneous rock |

Usually, a collection of minerals. Sometimes a rock may be made of materials that are not minerals | rock |
Small particle of soil or rock deposited by wind or water | sediment |
Rock that forms from sediments that are compacted and/or cemented together, or from the precipitation of material from a liquid | sedimentary rock |
Melted rock | magma |
Something left behind by a once-living organism. Fossils can be things like bones or footprints | fossil |
Particles of rock or minerals ranging in size from clay to giant boulder | sediment |
Changes in a rock that result from temperature increases when a body of magma contacts a cooler existing rock | contact metamorphism |
Flat layers in rocks due to squeezing by pressure | foliation |
Changes in rock that occur because of high pressure over a large area | regional metamorphism |
Formation of mineral grains from cooling magma | crystallization |
Transport of weathered materials and sediments by water, wind, ice, or gravity | erosion |
Solid state change in an existing rock due to high temperature and/or pressure that creates a metamorphic rock | metamorphism |
Dropping of sediments into a deposit | sedimentation |
Chemical or physical breakdown of rocks, soils, or minerals at Earth’s surface | weathering |
