Particle Sorting

QuestionAnswer
Settling Rate The speed of the process by which particulates settle to the bottom of a liquid and form a sediment.
Particle Size A notion introduced for comparing dimensions of soild, liquid, or gaseous particles.
Particle Shape Three different but related properties determine particle shape: form, roundness, and surface texture. Particle form is the overall shape of particles, typically defined in terms of the relative lengths of the longest, shortest, and intermediate axes.
Hydrodynamic Pertaining to forces in or motions of liquids.
Particle Density Density of material that particles are composed of or the average number of particles in unit volume or unit area.
Horizontal Sorting A form of graded bedding that occurs at the bottom of a body of water. The principle says that smaller colloids (particles) settle farther in the strata while larger particles settle closer to the source of water.
Graded Bedding One characterized by a systematic change in grain or clast size from the base of the bed to the top. Most commonly this takes the form of normal grading, with coarser sediments at the base, which grade upward into progressively finer ones.
Vertical Sorting The tendency of sediment to separate according to size and weight as it deposits. A cut-section of a vertically sorted deposit shows the largest, heaviest stones on the bottom layer, medium-sized stones in the middle and lightest sediment on top.
