| A | B |
| Rock | A naturally occurring solid mixture of one or more minerals |
| Rock Cycle | The constant changing in the form and structure of rocks |
| Igneous Rock | The type of rock that forms when magma or lava cools |
| Sedimentary Rock | The type of rock that forms when sediments become solid material. Forms near earth's surface |
| Metamorphic Rock | The type of rock that is changed by heat and pressure. Forms deep in the Earth |
| Erosion | When water, wind, ice, gravity move or transport sediment over the earth's surface |
| Weathering | Happens when water, wind, ice, and heat break down rock into sediment. |
| Deposition | When sediments stop moving and stay in position (deposited). Example: river banks, sand dunes, and deltas |
| Composition | The combination of elements and compounds that make up rock. |
| Texture | The sizes, shapes, and positions of the grains that make up a rock. |
| Types of Igneous Rock | Basalt, Granite, Obsidian, Pumice |
| Types of Sedimentary Rock | Shale, Conglomerate, Sandstone, Siltstone, Limestone |
| Types of Metamorphic Rock | Marble, Slate, Gneiss, Schist |
| Foliated | Metamorphic rock that has bands or layers |
| Non-foliated | Metamorphic rock that does not show bands or layers |
| Intrusive igneous rock | Igneous rock that cools from magma inside the earth and has large grains |
| Extrusive igneous rock | Igneous rock that cools from lava at the earth's surface. Has fine grains |
| Organic sedimentary rock | Sedimentary rock that forms from the remains of once living things |
| Clastic sedimentary rock | Sedimentary rock that forms from sediments being compressed and cemented together |
