Cerebral palsy is the result of a brain injury or a brain malformation. Individuals with cerebral palsy were most likely born with the condition, although some acquire it later. It was once thought that cerebral palsy was caused by complications during the birthing process.
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.hemical weathering refers to the processes by which rocks react with the atmosphere to form new substances. These reactions can alter a rock and transform the rock into sand, clays, and other minerals.
Hydration-This type of weathering occurs when rocks absorb water, and the resulting hydrogen and hydrate ions form new bonds with minerals present within the rock. This type of chemical erosion can actually result in a change to a new form of rock, such as the process by which gypsum is formed.hemical erosion, also called chemical weathering, causes the breakdown and decay or rocks or other geological features through a chemical process. This process can be the result of manmade activity, or the chemical composition of soil or water as it moves across the rock's surface.
