WebIn geology, a graded bed is one characterized by a systematic change in grain or clast size from one side of the bed to the other. Most commonly this takes the form of normal grading, with coarser sediments at the base, which grade upward into progressively finer ones. Such a bed is also described as fining upward. WebGraded beds have coarser (larger) sediment grains at the bottom, grading up to finer (smaller) sediment grains at the top of the bed; or the grading may occur in a sequence …
