Barnett - Rocks
Question | Answer |
---|---|
igneous | type of rock formed when lava or magma cools and solidifies |
sedimentary | type of rock formed by the lithification of sediment; most surface rock; only type to contain fossils |
metamorphic | type of rock formed when a pre-existing rock is changed by heat, pressure, or hot fluids |
rock cycle | model that illustrates the 3 types of rocks and how they can each change to any other type |
rock | consolidated mixture of minerals |
intrusive | type of igneous rock that cools inside the earth's crust; large grains |
extrusive | type of igneous rock that cools outside the earth's crust; small grains |
weathering | disintegration and decomposition of rock |
erosion | transportation of sediment by wind, water, or ice |
deposition | water, wind, or ice loses energy and drops sediments |
compaction | squeezing sediments together; caused by weight of sediment above it |
cementation | dissolved minerals are deposited in spaces between sediments and glues them together |
clastic | type of sedimentary rock made from weathered bits of rock and minerals |
chemical | type of sedimentary rock that forms when dissolved substances precipitate from a solution |
organic | type of sedimentary rock formed from the remains of once-living organisms |
contact | type of metamorphism that occurs when magma intrudes rock, exposing the rock to extreme temperatures |
regional | type of metamorphism that occurs during mountain building when tectonic plates collide; exposes rock to extreme heat and pressure |
foliated | type of metamorphic rock that has layers or bands |
non-foliated | type of metamorphic rock that does not form layers or bands |
lithification | process by which sediments are solidified to form solid rock |
bituminous | type of sedimentary coal; 3rd stage in the formation of coal |
anthracite | metamorphic form of coal; dark, shiny, dense, and produces the most energy when burned |
marble | metamorphic rock formed from the parent rock limestone |
stratification | sediments are laid down layer upon layer to form rock |
slate | metamorphic rock formed from the parent rock shale |
limestone | chemical sedimentary rock; forms in areas where there used to be marine organisms; gets carved out to form caves |
shale | sedimentary rock formed by mud and clay-sized particles |
