WebRocks do not change. Weathering and erosion are essentially the same thing. The two words can be used interchangeably. Erosion happens quickly. Erosion is always bad. Students tend to view the earth as static, stable, and unchanging. They often have difficulty believing that rocks can change or be worn down through the process of weathering. WebMay 6, 2024 · Chemical weathering works through chemical reactions that cause changes in the minerals. Most minerals form at high pressure or high temperatures deep in the crust, or sometimes in the mantle. When these rocks reach the Earth’s surface, they are now at very low temperatures and pressures. onshttp

WebChemical weathering occurs when the breakdown of rock results from chemical change in the rock, or the when the rock is dissolved away. The rate of these chemical reactions is … 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.
