Document Summary
Rock-a coherent, naturally occurring solid, consisting of an aggregate of minerals or a mass of glass. Cement-mineral material that precipitates from water and fills the spaces between grains, holding the grains together. Clastic sedimentary rock-sedimentary rock consisting of cemented- together detritus from the weathering of preexisting rock. Crystalline rock-rock that consists of mineral that grew when a melt solidified, and eventually interlock like pieces if a jigsaw puzzle. Igneous rocks-rock that forms when holt molten rock cools and freezes solid. Sedimentary rock-rock that forms by the cementing together of fragments broken off preexisting rock of by the precipitation of mineral crystals out of water solutions at or near the earth"s surface. Metamorphic rock-rock that forms when preexisting rock changes into new rock as a result of an increase in pressure and temperature and/or shearing under elevated temperatures. Equant-term for a gain that has the same dimensions in all directions.
