EXOGENETIC FORCE The exogenetic forces or processes also called as denudational processes or destruction forces or processes are originated from the atmosphere. These forces are continuously engaged in the the destruction of the relief features created by the endogenetic forces through there weathering erosional and depositional activities. Exogenetic processes are, therefore, planation processes. Denudation includes both weathering and erosion where weathering being a static process includes the disintegration and decomposition of rocks in situ whereas erosion is dynamic process which includes both removal of materials and their transportation to different destinations. Weathering is basically of three types viz. (a) Physical or mechanical weathering, (b) Chemical weathering and (c) Biological weathering. Weathering is very important for the biospheric ecosystem because weathering of parent rocks results in the formation of soils which are very essential for the sustenance of the
