Document Summary
The process by which rocks are broken down at the earth"s surface. The set of processes that loosen and move soils and rock downhill or downwind. Transfer of rock and soil downside by gravity. Presence or absence of soil and vegetation. Those small blocks are being dismembered, increasing the surface area. Increase the weathering, causing the water to allow itself to infiltrated the rock body. The process by which the minerals in a rock are chemically altered or dissolved. The principle agent of chemical weathering is water. Dipole molcules attacking the ionic molecule, separating the cation and anion from the water. Both sides are separating because of the dipole nature of the water. Small proportion of co2 gas molecule in air dissolves in rain droplets to form carbonic acid molecules. The chemical weathering of a raindrop transform into kaolinite due to the decomposition of the potassium ion and silica from feldspar.
