Question

Quizplus · Accepted Answer

Graded bedding refers to a sedimentary layer that shows a gradual change in grain or clast size from the bottom to the top of the bed. This typically occurs as a result of a decrease in energy in the depositional environment, allowing larger particles to settle out first, followed by progressively finer materials.
