| Mineral | A naturally formed, inorganic solid that has a definite crystal structure |
| Erosion | When wind, water, ice or gravity moves solid and sediment from one place to anothe |
| Rock | A naturally occurring solid mixture of one or more minerals and organic matter |
| deposition | When material gets laid down |
| Igneous Rock | Rock formed by magma that has cooled and solidified |
| Sedimentary Rock | Rock formed when sediments (pieces of rock) are deposited, then compacted and cemented together |
| Metamorphic rock | Rock formed under heat and pressure; structure, texture and composition of original rock changed |
| texture | Quality of a rock that is based on the size, shape, and position of the rocks grains |
| Composition | The chemical makeup of a rock; describes either the minerals or materials in a rock |
| Intrusive Igneous Rock | Rock formed from the cooling and solidification of magma under Earth’s surface |
| Extrusive Igneous Rock | Rock that forms as a result of volcanic activity on or near the Earth’s surface |
| Clastic Sedimentary Rock | Rock made of fragments of rocks cemented together by a mineral |
| Chemical-sedimentary rock | Rock that forms from solutions of dissolved minerals and water |
| Organic Sedimentary Rock | Rock that forms from the remains, or fossils, of animals, or decomposed plants |
| Fine Grained | Describes the texture of a rock: Rock that has a very small crystals, no crystals, or very small rock fragments |
| Coarse Grained | Describes the texture of a rock: Rock that has very large crystals, or fragments |
| Contact metamorphism | Rock that goes through metamorphism when magma moves through surrounding rock and heats it |
| Regional metamorphism | Rock that goes through metamorphism when pieces of the earth collide or when pressure builds up in rock deep below Earth’s surface |
| Foliated | The texture of metamorphic rock where the mineral grains are arranged in planes or bands |
| Non-Foliated | The texture of metamorphic rock where the mineral grains are NOT arranged in planes or bands |
