-rate of weathering positively linked to comportment or absence of mellowed mountains, and thus to plate plate tectonics 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 * icing the puck wedging- frozen seeping water * effects of heat- rocks dont conduct, spall (outer shell) breaks absent * plant roots- seeds germinate in cracks Chemical Weathering-Chemical Reactions (stabilize to surface temp) * c...If you fate to get a impelling essay, order it on our website: Ordercustompaper.com
