| Question | Answer |
|---|---|
| List all the examples of local winds. | Land breeze, sea breeze, mountain breezes, and valley breezes. |
| What are auroras and where are they found? | Auroras are polar winds. |
| Our ozone layer absorbs which type of harmful radiation from the sun? | UV (ultraviolet) rays |
| How much oxygen and carbon dioxide is found in our air? | |
| Which global wind blows away from the poles to the west? | Trade winds |
| What are the 2 most abundant gases found in the air? | Oxygen and carbon dioxide |
| Describe air pressure | The amount of air molecules around an object. |
| What happens to air pressure as altitude increases? | Air pressure decreases. |
| Describe jet streams. | Winds that travel globally. Planes use these. |
| What is the greenhouse effect? | It traps heat in our atmosphere. |
| Explain the 3 ways that heat is transferred. | Conduction, by touching heat or cold, convection, by being near heat or cold, and radiation, where the heat or cold sends rays of heat or cold. |
| Where do trade winds flow toward? | West |
| What does the Coriolis effect make the winds do? | Blow in circular patterns. |
| Describe the doldrums. | An area near 30 degrees latitude north and south and has little wind. |
| What is the ozone layer? Where is it found? | A layer of certain properties that protect the Earth from the sun's ultraviolet rays. |
| Describe the thermosphere. | The hottest layer in the atmosphere and found between the mesosphere and the stratosphere. |
| What is the most common atmospheric gas? | Nitrogen |
| What parts of the earth cools off faster and heats up faster? What does this unequal heating create? | Land cools and warms up faster. |
| What is smog? | When ozone and vehicle exhaust react with sunlight |
| Describe the movement of convection currents. | In a circular pattern. |
| Which instrument measures air pressure? | Barometer |
| What is significant about the troposphere? | There is weather and we live in it. |
| What kind of ways have humans created air pollution? | Vehicle exhaust and burning fossil fuels. |
| What is another name for the distance above sea level? | Altitude |
| What does the name of a wind tell you? | Where it blows. |
| How much of the sun’s energy actually reaches the Earth? | 2 billionths |
| What property are the layers of the atmosphere based on? | Oxygen |
| Which calm are is located around 30 degrees north and south latitudes? | Doldrums |
| What is the atmosphere? | Different layers that are based one property, oxygen. |
| List the three global winds and the two calm areas. | Global Winds:Polar easterlies, Westerlies, and Trade Winds Calm areas: Doldrums and Horse Latitudes |
| What is global warming? | When the greenhouse effect traps too much heat in our atmosphere. |
| If air mass increases, what happens to density? | It will increase. |
| What type of winds blow over short distances? | Local winds |
| How are winds created? | The Earth's rotation causes wind. |
