Particle Size Distribution Curve

For example: this curve falls inside only in sand region, hence this soil is definitely sand soil. Now this curve falls in gravel and sand region. So this is gravel sand soil. And this curve falls in silt and clay region. So this is silty clay soil. 4. we can determine the range of the grain size distribution of a soil.
