Q1:

Cohesive soils are generally

A plastic and also compressible

B elastic and also compressible

C plastic but incompressible

D none of these.

ANS:A - plastic and also compressible

Sand and other coarse (adhesive) soils are approximately incompressible so, clay is a link. With compressibility as it is a chohesive soil. Plastic soils (clays) are normally described as cohesive as a distinction from non-plastic soils (sands and gravels) which are often called granular or non-cohesive.

Moisture and air can be expelled out in Clay, So it's compressible.
