| Question | Answer |
|---|---|
| Rock | a naturally formed solid that may be igneous, sedimentary or metamorphic. It is made up of one or more types of minerals. |
| Rock Cycle | the set of natural processes that form, change, breakdown, and re-form rocks. |
| Sediment | solid materials such as rock fragments, plant and animal remains, or minerals that are carried by water or by air and that settle on the bottom of water or on the ground. |
| Sedimentary | rock formed as pieces of older rocks and other loose materials get pressed or cemented together or as dissolved minerals re-form and build up in layers. |
| Compaction | sedimentary rock formed when sediment is squeezed together under pressure (without any water present) |
| Cementation | sedimentary rock formed when water evaporates leaving sediment behind |
| Igneous | a type of rock formed when lava or magma cools and becomes solid |
| Extrusive | igneous rock that forms as lava cool on Earth’s surface (quickly) |
| Intrusive | igneous rock that forms as magma cools below Earth’s surface (slowly) |
| Metamorphic | rock formed as heat or pressure causes existing rock to change in structure, texture, or mineral composition |
