| Our ozone layer absorbs which type of harmful radiation from the sun? | UV rays |
| How much oxygen and carbon dioxide is found in our air? | Oxygen= 21% Carbon dioxide=less than 1% |
| Which global wind blows away from the poles to the west? | Polar easterlies |
| What are the 2 most abundant gases found in the air? | oxygen and nitrogen |
| Describe air pressure. | The weight of how much air there is on top of you. |
| What happens to air pressure as altitude increases? | The air pressure decreases. |
| Describe jet streams. | Narrow belts of high speed winds that blow in the upper troposphere and lower stratosphere |
| What is the Greenhouse effect? | When the sun's energy/heat is let into the area, but it doesn't flow back out. |
| Explain the 3 ways that heat is transferred? | Conduction is where the object that needs to be heated is touching another heated object. Convection is when the object is heated without touching the heated object. Radiation is when heat waves from the heated object heats the other object. |
| Where do trade winds flow to? | Flow towards the equator |
| What does the Coriolis effect make winds do? | They make them appear curved. Makes winds curve. |
| Describe the doldrums. | Doldrums are a calm type of wind that is near the equator.Dull |
| What is the ozone layer? Where is it found? | The ozone layer is a layer that protects humans from the harmful UV rays from the sun.The ozone layer is in the sky and atmosphere. |
| Describe the thermosphere. | Layer below the exosphere. |
| 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 heats faster, creates wind |
| What is smog? | A combination between smoke and fog. |
| Describe the movement of convection currents? | Warm air rises and then cools and falls. Moves in a cycle |
| Which instrument measures air pressure? | Barometer |
| What is significant about the troposphere? | Humans live in it and it has the oxygen that we need to breath. |
| What kind of ways have humans created air pollution? | Drive everywhere and do not carpool with friends. |
| What is another name for above sea level? | Altitude or elevation |
| What are global winds? | Winds that move in certain patterns around the globe. |
| What does the name of a wind tell you? | Tells you where the wind is coming from |
| 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 area is located around 30 degrees north and south latitude? | Horse latitudes |
| What is the atmosphere? | A bubble of air around the earth that keeps our oxygen in the earth. |
| List the 3 global winds and 2 calm areas. | Trade winds, Polar Easterlies, Westerlies, Doldrums, and Horse latitudes |
| What is Global Warming? | The unusual warming of an area. |
| If air mass increases what happens to density? | The density increases. |
| What type of winds blow over short distances? | local winds |
| How are winds created? | Unequal heating of the earth’s surface |
