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 involves the change in the composition of rocks, often leading to a 'break down' in its form. This type of weathering happens over a period of time. The types of Chemical weathering are: Dissolution: This occurs when rainfall is slightly acidic and gases in the air are added to it. This consequent mix can cause solution weathering of rocks. Hydration: Hydration is a form of chemical weathering that involves the rigid attachment of H+ and OH- ions to the atoms and molecules of a mineral. Hydrolysis: This is a chemical weathering process affecting Silicate minerals. is a chemical weathering process affecting Silicate minerals. In such reactions, pure water ionizes slightly and reacts with silicate minerals. Oxidation: This occurs within the chemical environment and makes the rocks soft.
