| A | B |
| Pycnocline | the middle zone of the ocean, contains 18% of ocean water in which density increases with depth |
| Latent Heat of Evaporation | the heat added to a liquid during evaporation |
| Surface Zone | the top layer of the ocean water, warmer and less salty than other layers |
| Latent Heat of Fusion | the heat removed from a liquid when it freezes |
| Thermostatic Properties | properties of water that act to moderate changes in temperature |
| Deep Zone | the densest, coldest and saltiest layer of the ocean, 80% of ocean water |
| Thermocline | a layer in the pycnocline where the ocean water decreases with temp and increases in salinity |
| Thermal Equilibrium | the condition in which the total heat of an incoming system equals the total heat outgoing, a balance |
| Thermal Inertia | the tendency of a substance to resist change in temperature with energy added or removed |
| Heat Budget | the total solar energy recieved on Earth during a set period of time and the total heat lost |
| Sensible Heat | the heat whose gain or loss is detectable by a thermometer |
