Question

Particle size of the medium 'Sand' lies between:

• A. 0.25 - 0.10 mm
• B. 0.50 - 0.25 mm
• C. 1.00 - 0.50 mm
• D. 0.10 - 0.05 mm

Hint:

Sand particle sizes vary: fine (0.05–0.25 mm), medium (0.25–0.50 mm), and coarse (0.50–1.00 mm).

Answer 1

The Correct Option is B

According to the USDA (United States Department of Agriculture) soil classification, the particle size for medium sand ranges from 0.25 mm to 0.50 mm. This size is coarser than fine sand (0.05 - 0.25 mm) and finer than coarse sand (0.50 - 1.00 mm). Hence, 0.50 - 0.25 mm falls within the correct range for medium sand.
