Physical Geology Notes

Physical Geology Notes Chapter Seven Weathering: chemic substance alteration and mechanical crack-up of gemstone and sediment. * depth of tenor/ piddle penetration * as distance of formation from approach rises, so does susceptibility to weathering * genuine weathering: The physical breakup of stonenrolls. * chemical weathering: The decomposition of rock and rolls and minerals caused by stability-increasing chemical reactions.

-rate of weathering positively linked to front end or absence of soften mountains, and thus to plate architectonics Physical Weathering-Mechanical Processes ( body of water, fire, roots) * development of joints- rock moved upward afterwards erosion, causes fractures -columnar joints in igneous rock * crystal growth- salts precipitated from seeping groundwater * rime wedging- frozen seeping water * effects of heat- rocks dont conduct, spall (outer shell) breaks apart * plant roots- seeds germinate in cracks Chemical Weathering-Chemical Reactions (stabilize to surface temp) * c...If you motivation to get a strong essay, order it on our website: Ordercustompaper.com
