| Term | Definition |
|---|---|
| salinity | The total amount of salt dissolved in a solvent. |
| Continental rise | The gently sloping area at the base of the continental slope. |
| Specific heat | The amount of energy required to raise the temperature of 1g of a substance by 1 C. |
| neap tide | A time of smallest tidal range due to the moon and sun being located at right angles to each other (during quarter moons.) |
| seafloor spreading | The process that creates new seafloor as plates move away from each other at the mid-ocean ridges. |
| Coriolis effect | The way in which the rotation of the earth bends the path of winds and resulting sea currents. |
| continental crust | The portion of the earth's crust that primarily contains granite, is less dense than oceanic crust, and is 20-50km thick. |
| subduction | The downward movement of 1 plate into the earth's mantle when 2 plates collide. |
| oceanic crust | The portion of the earth's crust primarily contains basalt, is relatively dense, and about 5km thick. |
| continental shelf | The gently sloped, shallow section of the edge of a continent, extending from the shore to the point where the slope gets steeper. |
| plate tectonics | A process involving the movement of large plates on the earth's mantle. |
| gyres | Large, mostly circular systems of surface currents drive by the wind. |
| Spring tide | A time of largest tidal range due to the gravitational pull of the aligned sun and moon (during full moon and new moon). |
| Continental Slope | The steeper section of a continental edge, extending seaward from the continental shelf. |
| mid-ocean ridge | A continuous chain of underwater volcanic mountains encompassing the earth. |
