| Question | Answer |
|---|---|
| List the examples of local winds. | Mountain,Sea,Land,and Valley breezes. |
| What are auroras and where are they found? | Auroras are shimmering lights formed by ions that radiate energy. Found in upper mesosphere and lower thermosphere. |
| Our ozone layer absorbs which type of harmful radiation from the sun? | Ultra Violet Light |
| How much oxygen and carbon dioxide is found in our air? | 21% oxygen and 1% Carbon Dioxide |
| Which global wind blows away from the poles to the west? | Polar Easterlies |
| What are the 2 abundant gases found in the air? | Oxygen and Nitrogen |
| Describe air pressure. | The amount of air molecules pushed on a surface. |
| What happens to air pressure as altitude increases. | Air pressure decreases as altitude increases. |
| Describe jet streams. | Narrow bands of strong winds that blow in the upper troposhere. |
| What is the greenhouse effect? | The warming of the surface and lower atmosphere of Earth that occurs when water vapor, carbon dioxide, and other gases absorb and reradiate thermal energy. |
| Where do trade winds flow toward? | The equator. |
| What does the Coriolis Effect make the winds do? | Curve |
| Describe the doldrums. | Very little wind, dull, and trade winds meet there. |
| What is the ozone layer? | Layer in the stratosphere that blocks out U.V rays. Layer of oxygen. |
| Where is the ozone layer found? | In the Stratosphere. |
| Describe the thermosphere. | Uppermost layer of atmosphere. Temperature increases due to solar radiation. Aurora Boralis occurs here. |
| Explain how Radiation transfers heat. | Transfers energy through electromagnetic waves. |
| Explain how Conduction transfers heat. | Transfer energy through direct contact. |
| Explain how Convection transfers heat. | Transfers energy by the circulation or movement of a liquid or gas. |
| What is the most common atmospheric gas? | Nitrogen |
| What parts of the earth cools off faster and heats up faster? | Land cools off and heats up faster. |
| What does unequal heating create? | Winds |
| What is smog? | Polluted air that forms when sunlight reacts with ozone and exaust. |
| Describe the movement of Convection Currents. | A circular momement. |
| Which instrument measures air pressure? | Barmometer |
| What is significant about the troposphere. | Weather occurs here and we live in it. |
| What kind of ways have humans created air pollution? | Burning of fossil fuels,exhaust, and chemicals. |
| What is another name for the distance above sea level? | Altitude or elevation |
| What are global winds? | Winds that blow long distances. |
| What does the name of a wind tell you? | Where the wind is coming from. |
| How much of the sun's energy actually reaches the earth? | 2 billionthes. |
| What Property are the layers of the atmosphere based on? | Based on the temperature changes. |
| Which calm area is located around 30 degrees north and south latitude? | Horse Latittudes |
| What is the atmosphere? | Mixture of gases that surround Earth. |
| List the 3 global winds and the 2 calm areas. | Polar Easterlies, Westerlies, and Trade Winds. Horse Lattitudes and Doldrums. |
| What is global warming? | A gradual increase in average global temperatures. |
| If air mass increase what happens to density? | Also increases. |
| What type of winds blow over short distances? | Local Winds. |
| How are all winds created? | Unequal heating of earths surface. |
