Final answer:
The slight forward movement caused by the circular orbit of waves is called Swell. Swell is a type of orbital progressive wave that occurs in oceans and other large bodies of water.
Step-by-step explanation:
The slight forward movement caused by the circular orbit of waves is called Swell. Swell is a type of orbital progressive wave that occurs in oceans and other large bodies of water. As waves move across the surface of the water, the particles of the medium follow a circular path from the crest to the trough.
