| Salinity | The proportion of dissolved salts in water |
| Ocean salinity | 35 grams of dissolved salts in every kilogram of water |
| What changes as depth increases? | Light and temperature decrease as pressure increases |
| Continental shelf | The gently sloping plain that forms an apron of water around most of the continents |
| Surface Current | A large stream of ocean water that moves continuously in the same direction |
| What causes surface currents? | Winds blowing across the surface of the ocean cause the continuous flow of surface currents |
| What are deep ocean currents caused by? | Deep ocean currents are caused by differences in the density of ocean water |
| Density currents | These are responsible for the slow mixing of water between the surface water and the deeper ocean. |
| What is upwelling? | Upwelling is when the warm water on the surface is pushed aside by the wind and then replaced by the cold water from underneath |
| Hydraulic action does what? | Hydraulic changes the landscape by water pounding on cracks in the rocks |
