| Question | Answer |
|---|---|
| List the examples of local winds. | Sea and land breeze |
| What are auroras and where are they found? | The auroras are shimmering lights in the ionosphere |
| 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? | There is 21 percent oxygen and less than 1 percent of carbon dioxide |
| Which global winds 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 force with which air molecules push on a surface. |
| What happens to the air pressure as altitude increases? | decreases |
| Describe jet streams. | A narrow band of high speed winds that blow in the upper troposphere and lower stratosphere. |
| What is the greenhouse effect? | The process by which gases in the atmosphere absorb thermal energy |
| Explain how radiation transfers heat. | EM waves {can't touch} |
| Explain how conduction transfers heat. | materials\direct contact |
| Explain how convection transfers heat. | energy through liquid or gases |
| Where do trade winds flow toward? | Flow towards the equator |
| What does the Coriolis Effect make winds do? | Curve |
| Describe the doldrums. | This is where trade winds meet; on the equator, very light winds-dull |
| What is the ozone layer? | Found in the stratosphere, layer of oxygen that absorbs most of the UV rays |
| Where is the ozone layer found? | The stratosphere |
| Describe the thermosphere. | Uppermost layer of the atmosphere Temp. increases due to solar radiation. Aurora Borealis occurs |
| 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; creates winds |
| What does this unequal haeting create? | Winds |
| What is smog? | Polluted air that forms when sunlight reacts with ozone and exhaust |
| Describe the movement of convection currents. | With a heat source, cold sinking air pushes warm less dense air up |
| Which instrument measures air pressure? | barometer |
| What is significant about the troposphere? | All the 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 or elevation |
| What are global winds? | Polar easterlies, westerlies, trade winds, clam areas, doldrums, and horse latitudes |
| What does the name of of a wind tell you? | Where it is blowing and where the wind is. |
| How much of the sun's energy actually reaches the Earth? | 2 billionths |
| 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? | Layer of gases that surround the Earth and protects us from UV and space objects |
| List the 3 global winds and the 2 calm areas. | Polar easterlies, Westerlies, and trade winds horse latitudes and doldrums |
| What is global warming? | The increase in average temperature on Earth |
| If air mass increases what will happen to the density? | Increases |
| What tpye of winds blow over short distances? | Local winds |
| How are all winds created? | The differences in air pressure. |
