| Question | Answer |
|---|---|
| Temperature | How hot or cold something is. |
| Humidity | The amount of water vapor in the air. |
| Circulation | The movement of air or water in a system. |
| Global winds | Large wind patterns that move air around Earth. |
| Jet stream | A fast-moving ribbon of air high in the atmosphere. |
| Atmosphere | The layer of gases surrounding Earth. |
| Ocean | A large body of salt water covering most of Earth. |
| Air mass | A large body of air with similar temperature and humidity. |
| Cold front | When cold air pushes under warm air. |
| Warm front | When warm air slides over cold air. |
| Precipitation | Water that falls from clouds (rain, snow, sleet, hail). |
| Temperature gradient | The difference in temperature between two places. |
| Hurricane | A powerful tropical storm with strong winds and heavy rain. |
| Thunderstorm | A storm with lightning, thunder, heavy rain, and sometimes hail. |
| Convection | Heat transfer by movement of liquids or gases. |
| Conduction | Heat transfer by direct contact. |
| Radiation | Heat transfer through waves (like sunlight). |
| Pacific Ocean | The largest ocean on Earth. |
| Trade winds (easterlies) | Steady winds that blow toward the equator from the east. |
| Westerlies | Winds that blow from the west toward the poles. |
| Global impacts | Effects that influence the entire world. |
| El Niño | A warming of Pacific Ocean surface waters that changes weather patterns. |
| La Niña | A cooling of Pacific Ocean surface waters that changes weather patterns. |
| Warm ocean current | A stream of warm water moving through the ocean. |
| Gulf Stream | A warm ocean current in the Atlantic Ocean. |
| Coastal regions | Areas near the ocean. |
| Oceanic conveyor belt | The global system of deep and surface ocean currents. |
| Coriolis effect | The bending of moving air and water due to Earth’s rotation. |
| Heat | Energy that makes things warmer. |
| Wind belts | Global zones where winds mostly blow in one direction. |
| Equator | The imaginary line around the middle of Earth. |
| Poles | The coldest areas at the top and bottom of Earth. |
| Ocean gyres | Large circular ocean currents. |
| Thermohaline circulation | Deep ocean currents caused by temperature and salt differences. |
| Surface temperatures | Temperatures at Earth’s surface. |
| Deep currents | Ocean currents far below the surface. |
| Regional climate | The usual weather in a specific area. |
| Climate zones | Large areas with similar climate conditions. |
| Maritime Tropical (mT) | Warm, humid air mass from oceans. |
| Maritime Polar (mP) | Cool, moist air mass from oceans. |
| Continental Tropical (cT) | Hot, dry air mass from land. |
| Continental Polar (cP) | Cold, dry air mass from land. |
| Continental Arctic (cA) | Very cold, dry air mass from Arctic land areas. |
| Seasons | The four yearly climate change (spring,summer,fall,winter |
| Sea breeze | Cool air that moves from the sea to the land during the day. |
| Coastal fog | Thick mist near the coast formed when warm air moves over cold ocean water. |
| Local climate | The usual weather conditions in a small area over a long time. |
| Moisture content | The amount of water vapor in the air |
| Land–sea breezes | Winds caused by temperature differences between land and water. Land heats and cools faster than water. |
| Hadley Cells | Large air circulation patterns near the equator where warm air rises and cooler air sinks. |
| Upwelling | Cold, nutrient-rich water rising from deep ocean to the surface. |
| Downwelling | Surface water sinking to deeper parts of the ocean. |
| Earth’s rotation | The spinning of Earth on its axis (takes 24 hours). |
| Atmosphere | The layer of gases surrounding Earth. |
