| Tidal Bore | a surge of tidal water that rushes upstream in a river that enters the ocean through a long bay attached to the ocean |
| Ebb Tide | Tidal current that flows towards the ocean |
| Flood Tide | Tidal current that flows toward the coast |
| The Moon and its gravitational pull on Earth's waters | the major cause of tides |
| radiation | radiation on the ocean is the sun's energy on the ocean surface. The sun's energy can evaporate the surface layer of the ocean. |
