The answer is True: Graded beds refer to sedimentary beds that show a decrease in grain size from bottom to top.

Explanation:

  • Graded bedding is a geological term used to describe a sedimentary layer that displays a systematic change in particle size from the bottom to the top. This typically occurs when a sediment-laden current slows down, causing the larger, heavier particles to settle first, followed by progressively smaller particles. This results in a bed that is coarser at the bottom and finer at the top, which is characteristic of graded beds.
