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. It can also impact fine motor skills, gross motor skills and oral motor functioning.
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.
RECOMMENDED LESSONS: Chemical Weathering This is when weathering involves the reaction of some chemicals on rocks. Some rocks (such as limestone and chalk) are more prone to chemical weathering than others such as granite.This is because limestone contains minerals such as calcium carbonate, which readily reacts with rainwater.This chemical reaction produces new soluble substances that are easily washed away.ECOMMENDED LESSONS: Chemical Weathering This is when weathering involves the reaction of some chemicals on rocks.
