| mixture of minerals, mineraloids, glass, or organic matter | rock |
| how rocks are constanstantly changed from one form to another | rock cycle |
| when molten rock cools, it forms this rock | igneous |
| magma that eventually reaches the Earth's surface | lava |
| igneous that form below the Earth's surface | intrusive |
| igneous rocks that form when lava cools on the Earth's surface | extrusive |
| rocks that cool so quickly no mineral grains form at all | glass |
| holes left behind where a rock formed by | trapped gases |
| egneous rocks that are dense, heavy, and dark-colored | basaltic (Hawaii) |
| igneous rocks that are light-colored and low density | granitic |
| rocks that have changed due to increased temperature and pressure | metamorphic rocks |
| shale changes into | slate |
| granite changes into | gneiss |
| metamorphic rock that has flattened mineral grains the line up in bands | foliated |
| metamorphic rock with no banding | nonfoliated |
| limestone changes into | marble |
| rock formed when sediments become pressed or cemented together | sedimentary rocks |
| small sediments stick together under pressure | compaction |
| large sediments cement together | cementation |
| type of rocks that often form layers | sedimentary |
| sedimentary rocks made of broken fragments compacted and cemented together | clastic |
| type of sedimentary rock that form from mineral solution that evaporates | chemical |
| sedimentary rocks that form from the remains of once-living things | organic |
