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.
How Fast Does Weathering Occur? Type of Rock Minerals that make up the rock determine how fast it weathers Rocks made of slow dissolving minerals will weather slowly Rocks made of fast dissolving minerals will weather quickly Some rocks weather more easily because they are permeable Climate Refers to the average weather conditions in one area Both chemical & mechanical weathering occur faster in wet climates. Chemical reactions occur faster at higher temperatures. Chemical weathering occurs faster in hot & wet climates Rainfall provides water needed for chemical weathering Definition of Permeable Characteristic of a material that contains connected air spaces or pores that water can seep through easily Spaces increase surface area of the rock Water seeps through, carrying chemicals that dissolve the rock Water also removes material broken down by weathering
