Main Body
Physical weathering involves temperature change and wave action. Chemical weathering involves hydration and carbonation. The various demudational agents start the process of chemical alteration of rocks. The impact of water runoff leads to hydration and leaching of elements from rocks. Temperature impacts the composition of the rocks. Volcanism leads to formation of igneous rocks. The process of oxidation leads to disintegration of rocks. Rusting and carbonation lead to physical breakup of rocks. The pressure action can alter the various layer formations in the rocks.
Water runoff impacts through hydration and leaching of elements from rocks. Temperature impacts the composition of rocks and can cause physical breakdown. Volcanism leads to formation of igneous rocks which undergo weathering. The process of oxidation leads to disintegration of rocks. Rusting and carbonation lead to physical breakup of rocks. Pressure action can alter the various layer formations in the rocks.
