Very poorly sorted indicates that the sediment sizes are mixed (large variance); whereas well sorted indicates that the sediment sizes are similar (low variance). In the field, sedimentologists use graphical charts to accurately describe the sorting of a sediment using one of these terms. [1]
A poorly graded soil will have better drainage than a well graded soil because there are more void spaces in a poorly graded soil. When a fill material is being selected for a project such as a highway embankment or earthen dam, the soil gradation is considered. A well graded soil is able to be compacted more than a poorly graded soil.
Poorly graded gravel Gravels with Fines. More than 12% fines Fines classify as ML or MH GM Silty Gravel Fines classify as CL or CH GC Clayey gravel Sands. 50% or more of coarse fraction passes No.4 sieve Clean Sands. Less than 5% fines Cu ≥ 6 and 1 ≤ Cc ≤ 3 SW Well-graded sand Cu < 6 and/or Cc < 1 or Cc > 3 SP Poorly graded sand Sands ...
Diagram showing well-sorted (left) and poorly sorted (right) grains. The size, form and orientation of clasts (the original pieces of rock) in a sediment is called its texture. The texture is a small-scale property of a rock, but determines many of its large-scale properties, such as the density, porosity or permeability. [18]

Well sorted (grains of approximately all one size) materials have higher porosity than similarly sized poorly sorted materials (where smaller particles fill the gaps between larger particles). The graphic illustrates how some smaller grains can effectively fill the pores (where all water flow takes place), drastically reducing porosity and ...
A half-cup serving of canned corn provides 2 grams of filling fiber and 2.5 grams of protein, as well as other nutrients like potassium, folate and choline, per the USDA. Canned Lentils.
Very poorly sorted indicates that the sediment sizes are mixed (large variance); whereas well sorted indicates that the sediment sizes are similar (low variance). speleothem A geological formation by mineral deposits that accumulate over time in natural caves. Speleothems most commonly form in calcareous caves due to carbonate dissolution ...
