Chemical Weathering Processes of Change

Chemical weathering can also result from exposure to water. Hydrolysis occurs when silicate minerals react with water so that the mineral recombines with the water molecule to form a new mineral.For example, consider the mineral potassium feldspar. Potassium feldspar is a fairly common mineral and can be found in igneous, metamorphic and sedimentary rocks.
