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.
Report Abuse. mechanical or physical weathering is caused by agents of when natural processes which break down rocks or materials into sediments, or small rocks. Mechanical weathering usually only changes the shape and size of a rock. Chemical weathering is caused by changes in a rock's chemical composition.For example, in a limestone cave, when Hydrocloric acid or acid rain comes in contact with the stalagmites and stalacatites, it will break them down.Rusting is another example of chemical weathering. The process is called Oxidation.hemical weathering is caused by changes in a rock's chemical composition.
