| Question | Answer |
| What are the three basic types of rocks? | Igneous metamorphic Sedimentary |
| A mixture of minerals, glass or organic matter | Rock |
| to make sediment from igneous rock requires... | Weathering and Erosion |
| Then transform sediment into sedimentary rock requires | Cementation and Compaction |
| Changing sedimentary rock into metamorphic rock requires | Heat and Pressure |
| to make a magma first before igneous rock requires... | Melting |
| To transform magma into igneous rock requires | Cooling and Crystallization |
| The two major categories of igneous rocks are... | EXTRUSIVE INTRUSIVE |
| The two main categories of sedimentary rocks are... | Clastic Non-clastic |
| The two major categories of metamorphic rocks are... | Foliated Non-foliated |
| The process in which different minerals in rock melt at different temperatures | partial melting. |
| The crystallization and removal of different minerals from the cooling magma is called | fractional crystallization. |
| magma or igneous rock rich in magnesium (Mg) and iron (Fe) and generally dark | Mafic |
| magma or igneous rock rich in feldspars and silica and generally light | Felsic |
| an igneous rock formed at the Earth’s surface | Extrusive |
| an igneous rock formed beneath Earth’s surface | Intrusive |
| What are the 4 locations where igneous rocks are formed? | Island Arcs Divergent plate boundaries Hot Spots Continental plate subduction zones |
| What are the two types of sedimentary rocks? | Clastic and Non-clastic |
| What are the two kinds of Non-clastic rocks? | Chemical and Organic |
| a sedimentary rock that forms when minerals precipitate from a solution or settle from a suspension | Chemical |
| sedimentary rock that forms from the remains of plants or animals | Organic |
| sedimentary rock that forms when fragments of preexisting rocks are compacted or cemented together | Clastic |
| Clastic rocks are classified by... | size, angularity, and sorting of the particles |
| The primary factors controlling metamorphism | Temperature and pressure |
| unequal pressure from different directions | Directed Pressure |
| Metamorphic Rock Texture in which minerals are arranged in layers or bands | Foliated |
| Foliation becomes more distinct with | increased temperature and pressure |
