3 TYPES OF WEATHERING AND THEIR PROCESSES
WEATHERING refers to the process of weakening, breaking up, and disintegration of the rock that forms the surface of the ground and that lie exposed to the weather. weathering is divided into 3 types namely; physical or mechanical weathering, chemical weathering, and biological weathering TYPES OF WEATHERING physical or mechanical weathering Mechanical or physical weathering is any of the various weathering processes that cause the physical disintegration of the exposed without any change in the chemical composition of rocks. 6 processes of physical/mechanical weathering. Frost action (freeze/thaw effect) this is the breaking of rock due to pressure exerted by freezing water into rock cracks or joints. When water freezes its volume increases. alternate freezing and thawing, therefore, exert pressure on the sides of cracks and joints in rock and this leads to the weakening and disintegration of rock. Pressure release this occurs when pressure is released when rock buried deep down in th...
