WebJan 11, 2024 · Chemical weathering works through chemical reactions that change the rock. No Longer Stable Most minerals form deep within Earth's crust. At these depths, temperatures and pressures are much higher than at the surface. Minerals that were stable deeper in the crust are not stable under surface conditions. That’s why chemical … WebWeathering causes the disintegration of rock near the surface of the earth. Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice.
