Down welling |
This sinking of denser/ water with more salinity to the bottom of the ocean |
|
|
Gyre |
A giant swirling vortex of water on the surface of the ocean |
|
|
High Tide |
The bulge of water caused by the gravitational pull of the moon |

|
Long shore Current |
move water and sediment parallel to the shore in the direction of the prevailing local winds. |

|
Low Tide |
The tides that form between the high tides |
|
|
Neap tide |
tides that have the smallest tidal range, and they occur when the Earth, the Moon, and the Sun form a 90o angle |

wave |
a long body of water curling into an arched form and breaking on the shore. |
