Explanation:
The sorting of sediments is the distribution of the particles or the grains of the sediments on the basis of the grain size. The sediments are classified into the following categories on the basis of their grain size : very poorly, poorly, moderately , well and finally, very well sorted.
The sorting is quantified by using the Inclusive Graphic Standard Deviation represent by
For a well-sorted layer of sediment, the Inclusive Graphic Standard Deviation is:
, diameter (phi units)
Therefore, in a well-sorted layer of sediment, all the grains will be of the same approximate size.
