The brain damage is caused by brain injury or abnormal development of the brain that occurs while a childâs brain is still developing â before birth, during birth, or immediately after birth. Cerebral palsy affects body movement, muscle control, muscle coordination, muscle tone, reflex, posture and balance.

While physical weathering is accentuated in very cold or very dry environments, chemical reactions are most intense where the climate is wet and hot. However, both types of weathering occur together, and each tends to accelerate the other.
In chemical weathering, minerals that were stable inside the crust must change to minerals that are stable at Earthâs surface. There are many types of chemical weathering because there are many agents of chemical weathering. Water is the most important agent of chemical weathering. Two other important agents of chemical weathering are carbon dioxide and oxygen.
