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.
Two important classifications of weathering processes exist â physical and chemical weathering; each sometimes involves a biological component. Mechanical or physical weathering involves the breakdown of rocks and soils through direct contact with atmospheric conditions, such as heat, water, ice and pressure.hile physical weathering is accentuated in very cold or very dry environments, chemical reactions are most intense where the climate is wet and hot.
