| non-foliated | describes the texture of metamorphic rock in which the mineral grains are NOT arranged in planes or bands |
| igneous rock | type of rock formed from lava or magma cooling |
| erosion | the process of wind, water & ice transporting soil & sediment from one location to another |
| sedimentary rock | type of rock formed by sediments compacting & cementing together |
| cementation | the process of the compacted sediment binding together during a rock formation |
| solidification | to make solid; make into a hard or compact mass; change from a liquid or gaseous state to a solid state |
| composition | the chemical makeup of a rock; describes either the minerals or other materials in the rock; the ÒingredientsÓ of something |
| coarse grained | igneous rock that has large crystal grains |
| metamorphic rock | type of rock formed from another type of rock being exposed to extreme heat & pressure changing it into another type of rock |
| weathering | the process of wind, water & ice breaking down rock |
| fine grained | igneous rocks that have either small or no crystal grains |
| foliated | describes the texture of metamorphic rock in which the mineral grains are arranged in planes or bands |
| extrusive igneous rock | rock that forms as a result of volcanic activity at or near the EarthÕs surface; cools fast, crystals wonÕt last |
| intrusive igneous rock | rock formed from the cooling & solidification of magma beneath the EarthÕs surface; cools slow, crystals will grow |
| re-crystallization | to become crystallized again |
| stratification | the process in which sedimentary rocks are arranged in layers |
| compaction | the consolidation of sediments resulting from the weight of overlying deposits |
| deposition | the process in which material is laid down or dropped |
| medium-grained | igneous rock that has medium sized crystal grains |
| Metamorphism | change in the structure of something |
