| Tides are daily or twice daily changes in local sea level (LSL). It is NOT just the ocean swishing around in the basin, though. | |

 | |  |
| They are however, caused by the gravitational pull of The sun and the moon, with the moon affecting it more than the sun due to it being closer (lunar tides and solar tides) | |
