a rock formed from the weathering products of preexisting rocks that have been transported, deposited, compacted, and cemented
a rock formed by the alteration of preexisting rock deep within Earth (but still in a sold state) by heat, pressure, and/or chemically active fluids
a model that illustrates the origin of three basic rocks types and the interrelatedness of Earth materials and processes
loose particles created by the weathering and erosion of rock, by chemical precipitation form solution in water, or from the secretions of organisms and transported by water, wind or glaciers
an igneous texture consisting of larger crystals embedded in a matrix of much smaller crystals
a compositional group of igneous rocks that indicate a rock is composed almost entirely of light-colored silicates, mainly quartz and feldspar
a compositional group of igneous rocks indication that the rock contains substantial dark silicate minerals and calcium rich plagioclase feldspar
the incorporation and transportation of material by mobile agent, such as water, wind, or ice
the process by which an agent of erosion loses energy and drops the sediment it is carrying
process by which sediments are squeezed together by the weigh of overlying materials driving out water
solidification of sediments by the deposition of dissolved minerals in the tiny spaces between the sedimentary particles
chemical sedimentary rock
sedimentary rock consisting of material that was precipitated from water by either inorganic or organic means
the change in mineral composition and texture of a rock subjected to high temperature and pressure within the Earth
the hot, watery solution that escapes form a mass of magma during the later stages of crystallization; Such solutions may alter the surrounding rock
the mechanical breakup of rock caused by the expansion of freezing water in cracks and crevices
type of weathering caused by the reducing pressure on a rock surface, allowing slabs of outer rock to break off in layers
the process by which the internal structure of a mineral is altered by the removal and/or addition of elements
the downslope movement of rock, regolith, and soil under the direct influence of gravity
the downward slipping of a mass of rock or unconsolidated material moving as a unit along a curved surface
slow-moving downslope movements of water-saturated, clay-rick sediment, most characteristic of humid regions
