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.
Chemical weathering and mechanical weathering form part of the natural processes that nature imposes on its subjects. Weathering happens when there is a breakdown, physical or chemical, to the surface mineral of rocks.This event is brought upon through natural elements such as water, gas, ice and plants.hemical weathering demands chemical reactions with minerals inside the rock and causes changes in rock composition. Sometimes this process will produce a different kind of product due to the reaction. Mechanical weathering only involves the physical breakage of rocks to smaller pieces of fragments.
