COASTAL PROCESSES IN ACTION You can observe coastal processes happening in real time. Traction is the movement of sediment as it rolls along the sea bed. When there is enough energy in the water to lift the particles—depending on their size—the sediment bounces along. This process is known as saltation. As these sediments move and collide with each other, they break into smaller pieces. Over time, this leads to the particles becoming smaller, smoother, and rounder. This erosional process is know
