| What are auroras and where are they found? | Shimmering lights.In the ionosphere which is in the thermosphere. |
| Our ozone layer absorbs which type of harmful radiation from the sun? | Ultra Violet rays. |
| How much oxygen and carbon dioxide is found in our air? | Oxygen takes up 21% while carbon dioxide takes up less than one. |
| Which global wind blows away from the poles? | Polar Easterlies. |
| What are the 2 most abundant gases found in the air? | Nitrogen and oxygen |
| Describe air pressure. | The measure of force with which air molecules push on a surface. |
| What happens to air pressure as altitude increases? | Air pressure decreases. |
| Describe jet streams. | Narrow belts of high speed winds. Found in the upper troposphere and lower stratosphere. |
| What is the greenhouse effect? | Gases in the atmosphere that absorb the thermal energy. |
| Explain the 3 ways heat is transferred. | Convection, thermal radiation, and conduction. |
| Where do trade winds flow? | Toward the equator. |
| What does the Coriolis Effect make winds do? | Due to the earths rotation winds and currents are caused to curve. |
| Describe the doldrums. | Low pressure around the equator. |
| What is the ozone layer? Where is it found? | In the stratosphere and protects us from harmful U.V. rays. |
| Describe the thermosphere. | The layer of the atmosphere that is furthest from the earth, and it's the hottest layer. |
| What is the most common atmospheric gas? | Nitrogen. |
| What part of the earth cools off faster and heats up faster? What does this unequal heating create? | Land heats up and cools down faster. |
| What is smog? | A mixture of the ozone, the sun, and exhaust. |
| Describe the movement of convection currents? | The cycle of warm air rising and cold air sinking. |
| Which instrument measures air pressure? | Barometer. |
| What is significant about the troposphere? | Gives us oxygen so we can live. |
| What kind of ways have humans created air pollution? | Humans cause pollution by burning fossil fuels, car exhaust, and using products with chemicals inside them. |
| What is another name for the distance above sea level? | Altitude. |
| What are global winds? | Winds that cover a large area. |
| What does the name of wind tell you? | What direction it flows or where it takes place. |
| How much of the suns energy actually touches the earth? | 2 billionth. |
| What property are the layers of the atmosphere based on? | Temperature. |
| Which calm area is located around 30 degrees north and south latitude? | Horse latitudes. |
| What is the atmosphere? | The layers of gases surrounding the earth. |
| List the three global winds and the 2 calm areas? | Westerlies, easterlies, trade winds, horse latitude, and doldrums. |
| What is global warming? | The increase in earths overall temperature. |
| If air mass increases what happens to density? | Decreases. |
| What type of winds blow over short distances? | Local winds. |
| How are all winds created? | Differences in air pressure. |
