Top-roping is not the same as belaying. However, belaying is involved in the activity of top-roping. In top-roping, a climber ties into the climbing rope. Then, on the other side of the rope, a belayer loads the rope into a belay device. As the climber moves upwards, the belayer takes slack out of the system to keep the climber safe if they fall. At the end of the climb, the belayer lowers the climber to the ground.
