Earth Science
| Question | Answer |
|---|---|
| Atmopshere | Thin layer of air that provides a protective covering around the planet. |
| Troposphere | Lowest of the Earth's atmospheric layers. |
| Stratosphere | The atmospheric layer above the Troposphere; Lower boundary of mesosphere. |
| Mesosphere | Above the stratosphere. |
| Ionosphere | Above the Mesosphere layer of electrically charged particles. |
| Thermosphere | Above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. |
| Exosphere | The outermost region of a planet's atmosphere. |
| Ultraviolet Radiation | Energy that comes from the sun to the earth. |
| Ozone Layer | An atmospheric layer in the stratosphere. |
| CFC's | Chemical compound found in: Fridges, AC's, Aerosol Spray, and foam packages. |
| Air Mass | Large body of air that has similar properties to the part of Earth's surface that it developed over. |
| Front | A boundary between two air masses of different density, moisture, or temperature. |
| Tornado | Violently rotating column of air in contact with the ground. |
| Hurricane | The most powerful storm, large swirling low-pressure that forms over the Atlantic ocean. |
| Blizzard | Winds are 56km/h, the temperature is low, the visibility is less than 400m in falling in blowing snow, and this persists for 3 hours. |
| Meteorologist | Person who studies the weather |
| Station Model | Shows the weather conditions at a specific location on earths surface. |
| Isotherm | Line that connects points of equal temperatures. |
| Isobar | Line that connects points of equal atmospheric pressure. |
| Occluded Front | (Purple triangles and semicircles) are three air masses of different temperatures: Colder air, Cool air, and Warm air. |
| Stationary Front | (Red semicircles, and Blue triangles) is when a boundary of air masses stops advancing. |
| Cold Front | (Blue Triangles) Occurs when colder air advances towards warm air |
| Warm Front | (Red Semicircles) Lighter, Warmer air advances over heavier, colder air |
