| Question | Answer |
|---|---|
| Through reading page 125, what does the author suggest is the most dangerous aspect to most humans about a tornado? | The injury caused by being hit by airborne debris. So cover up, and get to a safe place such as a basement, or in a bath tub. |
| Define weather: | Short term and local atmospheric conditions. |
| Contrast weather and climate. | Climate is annual, and over decades of observations. Weather is constantly changing and is influenced by local factors like elevation, or proximity to a major body of water. |
| Describe the weather variables. | Weather variables include the five key aspects of atmospheric conditions that might be noted including temperature, air pressure, wind, humidity, and clouds. |
| State the layer of the atmosphere upon which meteorologists focus, and tell why. | Troposphere as we live in it, and because it possesses most of the vapor content of the atmosphere. |
| Explain the major cause of weather. | Earth is forever trying to create an energy equilibrium between the equator and the poles. Thus, convection throughout Earth's atmosphere is constant. |
| Name the three major temperature scales, and upon which ESRT page a conversion scale may be found. | Celsius, Kelvin & Fahrenheit. See page 13 in the ESRT! |
| Name the instrument used to measure air temperature. | A thermometer. |
| Name the isolines used to connect points of equal temperature on a map. | Isotherms. |
| Define temperature: | An expression of the average kinetic energy of the particles of a body of matter. High temperature = high energy. |
| Discuss how latitude is key to air temperature. | Latitude determines the angle and duration of insolation. "High angle hot, low angle not". Long duration = hot, short duration = cool. |
| Explain how latent heat effects air temperature. | Latent heat is energy gained or lost during a phase change. Condensation and freezing warm the air. Evaporation and melting cool the air temperature. |
| Describe how the concentrations of Green House Gasses effect air temperature. | High concentrations of CO2 and Methane cause increased absorption of infra-red radiation thus raising the air temperature in our atmosphere. |
| How does the wind create friction with Earth's surface, and what is the byproduct? | Wind interfaces with the land and oceans as it flows across these surfaces. The byproduct is heat as kinetic and potential energy are converted. |
| Describe convection currents. | The process of energy exchange within our gaseous atmosphere. Convection currents and density driven. |
| How is temperature effected by rising air? | The air expands due to less air pressure. Fewer collisions of particles results in a lower air temperature. |
| How is temperature effected by sinking air? | The air compresses due to increased air pressure. More collisions between air particles results in higher air temperatures. |
| Please correctly answer the seven multiple choice questions found on page 128. | Please place your answers directly in your Regents Review book or photocopy. |
