4 DEC SS Q.18
- Option : C
- Explanation : Soil particles are classified by size. The size
of the soil particle gives texture to the soil and
determines the amount of air and moisture
that exists in the soil.
Clay particles measure less than 0.002 mm. Clay is the smallest type of soil particle.
Silt particles measure 0.06 mm to 0.002 mm. Silt's particles are larger than clay particles but smaller than sand particles. Sand particles measure 2.0 mm to 0.06 mm. Sand is the largest type of soil particle, and due to its size, allows quick drainage and plenty of airflow.
