| Rock | A group of minerals that are bonded together |
| Igneous | Hardening and cooling of lava/magma |
| Felsic | magma type high in silica, low in iron and Mg, light colored and low in density |
| Mafic | magma type low in silica, high in iron and Mg, it is dark colored and high in density |
| Large Crystals | seen with the naked eye; cooled slowly underground |
| Small Crystals | cooled fast, on top of earth |
| Intrusive | plutonic; cooled inside the earth |
| Extrusive | volcanic; cooled outside the earth |
| granite | an igneous rock, light in color, low in density; continental rock |
| basalt | igneous rock, dark color, high in density; oceanic floor |
| Sedimentary Rock | a rock that is formed through the deposition and cementation of rock fragments into layers |
| Crystalline | (chemical sedimentary rock) formed from evaporates and precipitates |
| Fossils | the preserved remains of plants/animals found in sedimentary rocks |
| Bioclastic Sedimentary Rocks | made of dead plants |
| Clastic | fragments |
| bioclastic | made from organic fragments |
| conglomerate | made from the largest variety of sediments |
| metamorphic | change |
| metamorphic rock | the change of pre-existing rocks by heat and pressure |
| stratified/stratification | the layering of sedimentary rocks |
| banding | the band of minerals in a metamorphic rock due to heat and pressure (reminds you of a tiger stripe)it has a wavy look |
| rock cycle | shows that all rocks, under the right circumstances, can change into another rock |
| most sedimentary rocks found here | on the continents |
| regional metamorphism | when large areas of rock are exposed to intense heat and pressure |
| contact metamorphism | when hot magma bakes the rock it comes in contact with - no foliation is produced |
