| Term | Definition |
|---|---|
| Temperature | A measure of how hot or cold something is, based on the average kinetic energy of its particles. |
| Humidity | The amount of water vapor in the air. |
| Circulation | The large-scale movement of air or water that transfers heat around Earth. |
| Global winds | Large wind systems that blow steadily over long distances across the planet. |
| Jet stream | A fast-moving, narrow band of strong winds high in the atmosphere. |
| Atmosphere | The layer of gases surrounding Earth. |
| Ocean | A vast body of saltwater covering about 70% of Earth’s surface. |
| Air mass | A large body of air with similar temperature and humidity throughout. |
| Cold front | The boundary where cold air pushes under and replaces warm air. |
| Warm front | The boundary where warm air moves over and replaces cold air. |
| Precipitation | Any form of water that falls from clouds (rain, snow, sleet, hail). |
| Temperature gradient | The difference in temperature between two areas. |
| Hurricane | A large, powerful tropical storm that forms over warm ocean water. |
| Thunderstorm | A storm with thunder, lightning, heavy rain, and sometimes hail or strong winds. |
| Convection | Heat transfer by movement of fluids (like warm air rising and cool air sinking). |
| Conduction | Heat transfer through direct contact between materials. |
| Radiation | Heat transfer through electromagnetic waves (like sunlight). |
| Pacific Ocean | The largest and deepest ocean on Earth. |
| Trade winds (easterlies) | Steady winds that blow from east to west near the equator. |
| Westerlies | Winds that blow from west to east in the middle latitudes. |
| Global impacts | Effects that influence the entire planet. |
| El Niño | A climate pattern where Pacific Ocean surface waters become warmer than normal, affecting weather worldwide. |
| La Niña | A climate pattern where Pacific Ocean surface waters become cooler than normal, affecting global weather. |
| Warm ocean current | A stream of warm water moving through the ocean. |
| Gulf Stream | A warm ocean current in the Atlantic that carries heat from the tropics toward Europe. |
| Coastal regions | Areas of land near the ocean. |
| Oceanic conveyor belt | The global system of deep-ocean currents that moves water around the planet. |
| Coriolis effect | The apparent bending of moving air and water caused by Earth’s rotation. |
| Heat | Energy that moves from warmer objects to cooler ones. |
| Wind belts | Large regions of Earth where prevailing winds blow in a certain direction. |
| Equator | An imaginary line around Earth’s middle that divides the Northern and Southern Hemispheres. |
| Poles | The northernmost and southernmost points on Earth (North and South Pole). |
| Ocean gyres | Large circular systems of ocean currents. |
| Thermohaline circulation | Deep-ocean movement driven by differences in temperature (thermo) and salinity (haline). |
| Surface temperatures | Temperatures at Earth’s surface (land or ocean). |
| Deep currents | Ocean currents that move far below the surface. |
| Regional climate | The typical weather patterns of a specific area over a long time. |
| Climate zones (Maritime Tropical, Maritime Polar, Continental Tropical, Continental Polar, Continental Arctic) | Categories of air masses based on where they form and their temperature and moisture characteristics. |
| Seasons | Periods of the year (spring, summer, fall, winter) caused by Earth’s tilt and orbit around the Sun. |
| Sea breeze | A wind that blows from the ocean toward land during the day. |
| Coastal fog | Fog that forms near the coast when moist air cools. |
| Hurricanes | Powerful tropical storms with strong winds and heavy rain (same as hurricane definition above). |
| Local climate | The typical weather conditions of a small, specific area. |
| Moisture content | The amount of water vapor in the air. |
| Land-sea breezes | Daily wind patterns caused by temperature differences between land and water. |
| Hadley Cells | Large circulation patterns near the equator where warm air rises and cooler air sinks. |
| Upwelling | The movement of cold, nutrient-rich water from deep ocean to the surface. |
| Downwelling | The sinking of surface water into deeper parts of the ocean. |
| Earth’s rotation | The spinning of Earth on its axis. |
