| Question | Answer |
|---|---|
| water | A compound (H₂O) essential for life that can exist as a solid, liquid, or gas |
| polarity | An uneven distribution of electrical charge in a molecule; water is polar |
| surface tension | The cohesive force at the surface of water that makes it act like a stretched skin |
| capillary action | The movement of water through small spaces due to cohesion and adhesion |
| cohesion | Attraction between molecules of the same substance |
| adhesion | Attraction between molecules of different substances |
| capacity | The ability of a substance to hold or store something, such as heat |
| temperature | A measure of how hot or cold something is, based on particle motion |
| agent | Something that causes change or produces an effect |
| climate | The long-term average weather patterns of a region |
| heat | Thermal energy that flows from warmer objects to cooler ones |
| convection | Heat transfer through the movement of liquids or gases |
| energy transfer | The movement of energy from one place or object to another |
| store | To hold energy for later use |
| absorb | To take in energy, such as heat |
| transmit | To pass energy from one place to another |
| energy | The ability to do work or cause change |
| deep ocean | Cold, dense water found far below the ocean surface |
| surface water | The upper layer of ocean water warmed by the Sun |
| Coriolis effect | The apparent bending of moving air or water due to Earth’s rotation |
| specific heat | The amount of heat needed to change the temperature of a substance |
| density | The amount of mass in a given volume |
| salinity | The amount of dissolved salt in water |
| current | A continuous flow of water in the ocean |
| thermohaline circulation | Global ocean movement driven by differences in temperature and salinity |
| ocean current | Large-scale movement of ocean water that transfers heat around Earth |
| wind patterns | The general movement of air across Earth’s surface |
| specific heat capacity | The amount of energy required to raise the temperature of a substance by one degree. |
| latent heat | Energy absorbed or released during a phase change without changing temperature |
| evaporation | The process where liquid water changes into water vapor |
| condensation | The process where water vapor changes into liquid water |
| surface tension | The force created by cohesion at the surface of water |
| energy circulations | The continuous movement of energy through Earth systems |
| thermocline | A layer in the ocean where temperature changes rapidly with depth |
| halocline | A layer in the ocean where salinity changes rapidly with depth |
| melting | The change of a solid into a liquid |
| freezing | The change of a liquid into a solid |
| wave formation | The creation of waves caused mainly by wind transferring energy to water |
| heat transfer | The movement of thermal energy from warmer areas to cooler areas |
