Document Summary
In a test, draw a diagram, add a label, and a short desription. Equant - all sides are fairly equal. Rod shape - one dimention is longer than the others. Tabular - one dimention shorter than the others. In a test, draw multiple objects of different shapes but that have the same quality. Label it highly rounded or whatever, smooth surface and add on can be any shape . Roundness implies that a particle has a smooth surface, no sharp edges, no corners, it. Angularity implies that a particle has a rough or jagged surface with sharp edges and may be oval, spherical, irregular e. t. c. corners; the overall shape is variable. Sphericity is how close the particle is to being an identical shape of a sphere, but its surface may be angular or rounded. The better the sorting is, the more likely we find rounded particles. Rivers and stuff do a lot of sorting.
