WebWeathering is the mechanical and chemical hammer that breaks down and sculpts the rocks. Erosion transports the fragments away. Working together they create and reveal marvels of nature from ... WebChemical weathering increases as: Temperature increases: Chemical reactions proceed more rapidly at higher temperatures. For each 10 o C increase in average temperature, the rate of chemical reactions doubles. Precipitation increases: More water allows more chemical reactions.

This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals. did kenny rogers write the gambler

"WebChemical weathering takes place when water, oxygen, carbon dioxide, and other chemical substances react with rock to change its composition. These reactions convert some of the original primary minerals in the rock to secondary minerals, remove other substances as solutes, and leave the most stable minerals as a chemically unchanged resistate.
