| Bathypelagic Zone | The zone of the ocean between 1000 and 4000m deep which receives no sunlight |
| Benthic Zone | The lowest depth region in any body of water including the surface of the substrate |
| Benthos | The community of organisms found in the benthic zone |
| Carbon Sink | A natural environment that absorbs carbon dioxide from the atmosphere faster than it releases it |
| Coriolis Effect | A force that results from the Earth's rotation that causes objects or particles in motion to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere |
