mineral grains and decayed organic matter (solid
particles) with liquid and gas in the empty spaces
between the solid particles, and it supports
structural foundations.

earth. It includes the application of the principles
of soil mechanics and rock mechanics to the
design of foundations, retaining structures and
earth structures.

s defined as a natural aggregate of mineral
grains, loose or moderately cohesive, inorganic in
nature, that have the capacity of being separated
by means of simple mechanical process, e.g. by
agitation in water.

Answer 24

Soil

Question 25

is defined as hard and compact natural aggregates of mineral grains cemented by strong and more or less permanent bonds.
