| (i)Etrusive rock | is igneous rock ormed from lava on the Earth's surface |
| (i)Intrusive rock | is ingeous rock that is formed when magma hardens beneath the earth's surface |
| (i)What does rapidly cooling lava form? | fine grained igneous rock with small crystals |
| (i)What does slowly cooling magma form? | coarse grained rocks with large crystals |
| (i)lava up and.. | magma down |
| (i)extrusive up and.. | intrusive down |
| (i)magma with a a lot of silica forms... | lighter rock |
| (i)lava with little silica forms... | darker rock |
| (s)Sediment | small, sold pieces of material that come from rocks or other living things |
| (s)Sedimentary rock forms when...? | sediment is deposited by wind and water |
| (s)4 forming processes... | Erosion, Deposition, Compaction, and Cementation |
| (s)EROSION | running water, wind, or ice loosen and carry away fragments of rock |
| (s)DEPOSITION | the process by which sediment settles out of the water or wind carrying it |
| (s)COMPACTION | the process that presses sediment together |
| (s)CEMENTATION | the process in which disolved minerals crystallize and glue parcticles of sediment together |
| (s)3 types of sedimentary rocks? | CLASTIC, ORGANIC, and CHEMICAL |
| (s)CLASTIC ROCK | forms when rock fragments are squeezed together |
| (s)ORGANIC ROCK | forms where the remains of plants and animalsare deposited in thick layers |
| (s)CHEMICAL ROCK | forms when minerals that dissolved in a solution crystallize |
| (m)What can change any rock into metamorphic rock? | heat and pressure from below the Earth's surface |
| (m)How do Geologists classify metamorphic rocks? | according to the arrangement of the grains that make up the rock |
| (m)Names of each classifications? | Foliated and Nonfoliated |
| (m)FOLIATED | Metamorphic rocks that have their grains arranged in parallel layers or bands |
| (m)NONFOLIATED | The mineral grains are arranged randomly |
