| Question | Answer |
|---|---|
| List the examples of local winds. | Sea and land breezes |
| What are auroras and where are they found? | shimmering lights found in the ionosphere |
| Our ozone layer absorbs which type of harmful radiation from the sun? | UV |
| How much oxygen and carbon dioxide is found in our air? | 21%-oxygen less than 1%-carbon dioxide |
| Which global wind blows away from the poles to the west? | polar easterlies |
| What are the 2 most abundant gases found in the air? | Nitrogen and oxygen |
| Describe air pressure. | the measure of the force with which air molecules push on a surface |
| What happens to air pressure as altitude increases? | As altitude increases, air pressure decreases |
| Describe jet streams. | Narrow belts of high speed winds that blow in the upper troposphere |
| What is the greenhouse effect? | the process by which gases in the atmosphere absorb energy |
| Explain the 3 ways that heat is transferred. | convection-energy through gas or liquid conduction-material/direct contact radiation-EM waves (can't touch) |
| Where do trade winds flow toward. | flow towards the equator |
| What does the Coriolis Effect make winds do? | makes winds curve |
| Describe the doldrums. | this is where trade winds meet;on the equator, very light winds/dull |
| What is the ozone layer? | layer of oxygen that absorbs most of the sun's UV rays |
| Where is the ozone layer found? | the statosphere |
| Describe the thermosphere. | Uppermost layer of the atmosphere with temp. that increase due to solar radiation. the Aurora Borealis occurs here |
| What is the most common atmospheric gas? | Nitrogen |
| What parts of the Earth cools off faster and heats up faster? | Land |
| What does unequal heating of the Earth create? | Local winds |
| What is smog? | Polluted air that forms when sunlight reacts with ozone and exaust |
| Describe the movement of convection currents? | with a heat source, cold, sinking, dense air pushes warm, light, lees dense air- continues in a cycle |
| Which instrument measures air pressure? | Barometer |
| What is significant about the troposhere? | weather occurs here |
| What kind of ways have humans created air pollution? | burning fossil fuels- exhaust, chemicals |
| What is another name for the distance above sea level? | altitude and elevation |
| What are global winds? | the combination of convection cells found every 30 degrees latitude and the Coriolis Effect produces patterns of air circulation |
| What does the name of a wind tell you? | where it 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? | temp. |
| Which calm area is located around 30 degrees north and 30 degrees south latitude? | Horse Latitudes |
| What is the atmosphere? | a mixture of gases with layers that protect our Earth |
| List 3 global winds and 2 calm areas. | Global Winds-trade, westerlies, polar easterlies Calm Areas-horse latitudes, doldrums |
| What is global warming? | heat from the sun enters our atmosphere and gets trapped |
| If air mass increases what happens to density? | increases |
| What type of winds blow over short distances? | local winds |
| How are all winds created? | air pressure |
