Weathering, Erosion, and Mass-Wasting Processes

2020-8-26 · Hydration is a process where mineral structure in the rock forms a weak bond with H 2 0 which causes the mineral grains to expand, creating stress which causes the disintegration of the rock. Hydration often produces a new mineral compound that is larger than the original compound. The increased size expanse the rock and can lead to decay.
