Module 3 study questions
| Question | Answer |
|---|---|
| Atmosphere | The mass of air surrounding a planet |
| Atmospheric pressure | The pressure exerted by the atmosphere on all objects within it |
| Barometer | An instrument used to measure atmospheric pressure |
| Exosphere | The region of the atmosphere above an altitude of 460 kilometers |
| Heat | Energy that is being transferred |
| Heterosphere | The upper layer of earth's atmosphere, which exists higher that 80 kilometers (50 miles) above sea level |
| Homosphere | The lower layer of earth's atmosphere, which exists from ground level to roughly 80 kilometers (50 miles) above sea level |
| Ionosphere - | The region of the atmosphere between the altitudes of 65 kilometers and 330 kilometers where the gases are ionized |
| Jet stream | A narrow band of high-speed winds that circle the earth, blowing from west to east |
| Mesosphere | The region of the atmosphere that spans altitudes of 48 kilometers to 80 kilometers (50 miles) |
| Stratosphere | The region of the atmosphere that spans altitudes of 11 kilometers to 48 kilometers (30 miles) |
| Temperature | A measure of the energy of motion in a substance's molecules |
| Thermosphere | The region of the atmosphere between altitudes of 80 kilometers and 460 kilometers |
| Troposphere | The region of the atmosphere that extends from ground level t roughly 11 kilometers (7 miles) above sea level |
| In what part of the atmosphere would you study weather? | Troposphere |
| In what part of the atmosphere would you study the Ozone layer? | Stratosphere |
| In what part of the Homosphere does temperature increase? | Stratosphere |
| If there is a leak of air in a barometer, what would happen to the height in the liquid? | It would decrease |
| Why is the Ozone hole a seasonal Phenomenon? | Polar Vortex only happens in the South Pole and only during the months of Aug-Nov. |
| Where are the Thermosphere and Exosphere located? | Heterosphere |
| What is located in the Homosphere? | Troposphere, Stratosphere, Mesosphere |
| What makes it possible for CFCs to travel up to the ozone layer and begin destroying ozone? | Polar Vortex |
| Does Temperature decrease with increasing altitude in the troposphere? | yes |
| If molecules are increasing in speed, will the temperature increase or decrease? | Increase |
