rock and mineral terms
| Question | Answer |
|---|---|
| What are metamorphic rocks that do not exhibit foliation? | nonfoliated rocks |
| Magma that reaches earth's surface is called? | lava |
| Molten rock found at depth under the ground is called? | magma |
| Metamorphism associated with mountain building is called? | regional metamorphism |
| Metamorphic rocks with a layered appearance have what type of texture? | foliated texture |
| Sedimentary rocks made from solid, weathered particles are called? | detrital sedimentary rocks |
| Sedimentary rocks precipitated by water that evaporates are called? | chemical sedimentary rocks |
| A sedimentary rock made of material deposited from solution by the evaporation of water is? | evaporite |
| Changes in rock caused by the heat of a nearby magma body is called? | contact metamorphism |
| The parallel layers of sedimentary rocks are called? | strata |
| Rocks formed by the crystallization of magma are called? | igneous rocks |
| The formation and growth of a crystalline substance from a liquid is called? | crystallization |
| The conversion of sediments by compaction and cementation is called? | lithification |
| The disintegration and decomposition of rocks at the earth's surface is called? | weathering |
| Igneous rocks that form from lava on the earth's surface are called? | extrusive or volcanic |
| Igneous rocks that form from magma below the earth's surface are called? | intrusive or plutonic |
| The size, shape and distribution of the particles that make up a rock is called the rock's? | texture |
| A texture in which the crystals are too small for the individual minerals to be seen with the unaided eye is called? | fine-grained texture |
| A texture in which the crystals are large enough to be seen and identified is called? | coarse-grained texture |
| A texture in which there are no crystals due to very rapid cooling is called? | glassy |
| A texture in which large, visible crystals are imbedded in a fin-grained matrix or background is called? | porphyritic |
| Rocks formed from the weathered pieces of preexisting rocks by lithification are called? | sedimentary rocks |
| Rocks formed by the alteration of preexisting rocks by heat, pressure and chemically active fluids are called? | metamorphic rocks |
