Waves
| Wave | a long body of water curling into an arched form and breaking on the shore. |
| Wave length | In physics, the wavelength of a sinusoidal wave is the spatial period of the waveâthe distance over which the wave's shape repeats, and thus the inverse of the spatial frequency. |
| Wave crest | A crest is the point on a wave with the maximum value or upward displacement within a cycle. A crest is a point on the wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycl |

| Deep ocean current | Deep ocean currents are driven by density and temperature gradients. |
| Surface current | The water at the ocean surface is moved primarily by winds that blow in certain patterns because of the Earth's spin and the Coriolis Effect. |
| Salinity | the concentration of dissolved salts in water etc., usually expressed in parts per thousand by weight. |
| Density | degree of consistency measured by the quantity of mass per unit volume. |
| Spring tide | a tide just after a new or full moon, when there is the greatest difference between high and low water. |
| Neap tide | a tide just after the first or third quarters of the moon when there is the least difference between high and low water. |
| Gravitational pull | Gravity, or gravitation, is a natural phenomenon by which all things with mass are brought toward one another, including objects ranging from atoms and photons, to planets and stars. |
