Answer |
| Volcanic | term that refers to molten (igneous) rock rock that is extrusive. it comes from cooled lava -which is magma that is found on surface |
| uniformitarianism | theory that states that earth was formed by processes that are still in existance today, such as rock formed by volcanic activity and from rock that is changed by heat and pressure or formed from sediments. |
| Texture | depends on the size , shape, and arrangement of the mineral crystals |
| stratification | visible layers found in sedimentary rocks that helps one identify the type of rock caused by a change in the type of sediments being laid down |
| sedimentary | one of the 3 main catagories of rock classification. rocks created by sediments being cemented or formed by evapoation ---most of earth's surface is covered by sedimentary rocks |
| rock | group of minerals bound together together in some way. |
| chemical rock | sedimentary rocks formed from mineral's precipitate by evaporation or by chemical action |
| clastic rock | sedimentary rocks formed from fragments of other rocks |
| contact metamorphism | the process of rock-forming that results when hot magma forces its way into overlying rock and changes that rock |
| felsic | light-colored, high-silica rocks |
| fossils | the remains, impressions, or other evidence of the former existence of life preserved in rock |
| igneous rocks | rocks formed by the solidification of hot molten rock material called magma |
| mafic rocks | dark-colored, low-silica rocks |
| magma | the hot liquid rock beneath Earth's surface |
| metamorphic rocks | rocks formed by the effect of heat, pressure, and chemical action on other rocks |
| organic rocks | sedimentary rocks formed from the remains of plants and animals |
| plutonic | rocks, usually igneous, formed at great depths |
| regional metamorphism | process of rock forming which results from large areas of rocks being under intense heat and pressure of mountain building efforts |
| Rock cycle | process of 1. forming rock from molten magma, and 2. the transformation of that rock to sedimentary or metamorphic rock and then the subsequent remelting of that rock. |
