Used for studying weather vocabulary, layers of the atmosphere, and the water cy
| Term | Definition |
|---|---|
| Temperate Zone | Moderate temperature area, located between the latitudes of the tropics and polar regions |
| Cold Front | Transition zone where a warm air mass is replaced by a cold air mass |
| Low pressure | A region where atmospheric pressure is lower than surrounding locations. Brings warm weather, storms, and rain. |
| Isobars | Lines connecting points of atmospheric pressure |
| Salinity | Saltiness of a liquid. Affects density of water along with temperature. |
| Coriolis Effect | The curvature of global winds due to the Earth's rotation |
| Air Mass | Volume of air based on temperature and water vapor content |
| Ionosphere | An extension of the thermosphere |
| Warm Front | Zone where a colder air mass is replaced with a warm air mass |
| Front | The boundary between two air masses that have different temperatures or humidity |
| Stationary Front | An unmoving front that acts as a boundary between two different air masses, neither of which is strong enough to replace the other |
| Cyclones | Areas of low pressure |
| Anti-Cyclones | Areas of high pressure |
| High Pressure | A region where atmospheric pressure is higher than that of surrounding areas. Brings cool weather and clear skies. |
| Heat | Transfer of energy between objects of different temperatures |
| Thermal Energy | The type of energy heat is |
| Conduction | Heat transfer through solids and direct contact |
| Convection | Heat transfer through liquids or gases |
| Radiation | Heat transfer through electromagnetic waves or empty space |
| Specific Heat Capacity | Amount of energy needed to heat one kilogram of a substance by 1ºC |
| Atmosphere | All of the air that surrounds Earth |
| Hydrosphere | All of Earth's water |
| Lithosphere | All of the Earth (rocks and minerals) on Earth |
| Biosphere | All life on Earth |
| Layers of the Atmosphere | Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere |
| Troposphere | Layer closest to Earth's surface where weather and life happens |
| Stratosphere | Above troposphere and is where the ozone layer is located |
| Mesosphere | Above stratosphere and is the coldest layer |
| Thermosphere | Above mesosphere and is extremely hot because of the UV and X-ray radiation that occurs. Auroras also happen here. |
| Exosphere | Outermost layer of the atmosphere composed mainly of Hydrogen and Helium. Artificial satellites located here. |
| Runoff | Water that flows across land across land and collects in larger bodies of water |
| Infiltration | The process by which water on the ground surface enters the soil. |
| Condensation | Water vapor in the air getting cold and turning back into a liquid |
| Evaporation | Water turning into water vapor and ascending into the Earth's atmosphere |
| Precipitation | The process by which water falls down onto the earth. May be in the form of rain, snow, hail, or sleet. |
| Transpiration | The process by which moisture is carried through plants |
| Rain Gauge | Measures precipitation |
| Psychrometer | Measures humidity |
| Barometer | Tells atmospheric pressure |
| Weathervane | Measures wind direction |
| Anemometer | Gives wind speed |
| Nephoscope | Measures cloud altitude and direction |
| Occluded Front | Front in which 2 cold air masses merge and force warm air between them. The warm air rises quickly, and strong winds and heavy precipitation occurs. |
| El Niño | Warming of the oceans and Earth. Is associated with wet, rainy weather in the United States |
| La Niña | Cooling of the oceans and Earth. Is associated with dry weather in the United States. |
