2 Answer the following. Describe how you would expect residual (a) soils to change with increasing depth. (b) Give an example of an organic soil (c) What is the usual composition of backswamp deposits? What is the usual composition of alluvial- lacustrine deposits? Give an example of a collapsing soil that we discussed in class. (e) Why is it considered \"collapsing?\" References: Ref1, Ref2 Solution a) With increasing depth residual soil deposits will increase because at the top of the surface, erosion will occur and new soils are occupying the older ones. b) Peat is an organic soil generated from decomposed vegetative matter. c) After flood Clays and silts are getting occupied. Hence it is composed of silts and clays. d) Composition of allluvial and lacustrine is with silts. These soils are mainly silty soils. e) Aeolin solis are collapseble soils. These soils are compacted even under low pressure. Hence these are called collapsible soils..
