Geology Review

Sediment- consists of loose fragments of wavers or minerals broken off bed contestation, mineral crystals that absolved directly out of pee, and shells. Sediment rock- rock that forms at or near that surface of the Earth by the precipitation of minerals from wet solutions, by the growth of skeletal framework in organisms, or by the cementing together of shell fragments or of loose grains derived from pappaulate rock. Weathering- processes that break up and corrode solid rock, eventually transforming it into sediment. material weathering- also mechanical weathering, breaks intact rock into unconnected grains or chunks. Boulders, cobbles, pebbles, sand, silt, mud. Jointing- natural cracks that form in rocks due to removal of appoint or due to cooling. Some junctions are fairly planar, whatsoever curving, some irregular. Frost wedging- when the pee trapped in a colligation freezes, it forces the joint open and may cause the joint to grow. Root wedg ing- tree roots that grow into joints can play off those joints open. Salt wedging- pushes apart the surrounding grains and so weakens the rock that when on the fence(p) to wind and rain, the rock disintegrates into separate grains. Thermal expansion- creates forces in the rock sufficient to make the outer part of the rock spall, or break off into sheet-like pieces.

Animal attack- burrowing creatures, from earthworms to gophers, push open cracks and pop off rock fragments. Chemical weathering- the chemical reactions that alter or repeal minerals when rock comes in contact with water solutions or air. Saprolite- chemical weathering in warm, wet climates can produce a bo ttom of rotten rock called saprolite. Dis! solution- minerals dissolve into water Hydrolysis- water chemically reacts with minerals and breaks them down. Transforms felspar into clay. Oxidation- reaction during which an element loses electrons as an oxidation reaction. Hydration- the acculturation of water into the crystal structure of...If you want to get a sufficient essay, order it on our website: OrderEssay.net
