Basics of Soil mechanics 
Karl Terzaghi is father of soil mechanics .
The process of formation of soil is term as Pedogenesis.
The soil is form due to weathering of rock which may be carried out either physically or chemically .
Physical agency involved in weathering are running water ,ice gravity , wind etc . and chemical agency are involved in weathering are oxidation carbonation reduction etc.
If weather material is retain over parent rock ,soil is term as residual soil and if it transported then soil is term as transported soil .
