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.
Physical weathering does not produce any change in the chemical composition of the rock rather the rock becomes broken up into fragments smaller than the initial volume of rock. Chemical weathering, on the other hand, are chemical changes undergone by rocks exposed near the earthâs surface.Rocks typically form in pressure and temperature conditions far removed from those at or near the earthâs surface.eathering Weathering is the process of breakdown of rocks at the surface of the earth and reflects an adjustment of rocks to conditions of temperature, humidity and fluid composition on the earthâs surface.
