atmosphere and winds
study tool for atmosphere and winds
| Question | Answer |
|---|---|
| List the examples of local winds. | mountain and valley breezes and land and sea breezes |
| What are auroras and where are they found? | in the thermosphere that is energy as shimmering lights |
| Our ozone layer absorbs which type of harmful radiation from the sun? | ultraviolet rays |
| How much oxygen and carbon dioxide is found in our air? | oxygen 21% carbon dioxide 1% |
| 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. | air pressure is the measure of the force with which air molecules push on a surface |
| what happens to air pressure as altitude increases? | the air pressure decreases |
| describe jet streams. | narrow belts of high speed winds |
| What is the greenhouse effect? | heat from the sun comes in and is trapped by the atmosphere and can't get out |
| explain the 3 ways that heat is transferred. | radiation transfer as electromagnetic waves, conduction is transfer though a material, and convection is transfer though thermal energy |
| Where do trade winds flow toward? | 30 degrees latitude and almost along the equator |
| what does the Coriolis Effect make the winds do? | due to the earth's rotation winds and currents are caused to curve |
| describe the doldrums? | low pressure close to the equator |
| What is the ozone layer? Where is it found? | the ozone layer protects the sun from dangerous heat waves from the sun and is located at the statosphere |
| Describe the thermosphere. | the thermosphere is the hottest and farthest layer and includes the ionosphere |
| 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 heats up faster and water cools off the fastest and it creates wind |
| what is smog? | smoke and fog from exhaust from cars and other things made by humans |
| Describe the movement of convection currents. | the cycle of warm air rising and cooling air creating a circular movement |
| which instruments measures air pressure? | barometer |
| what is significant about the troposphere? | every living thing live in the troposphere |
| What kind of ways have humans created air pollution? | humans drive cars and cars run on oil and and burns the oil and give out exhaust |
| What is another name for the distance above sea level? | altitude |
| What are global winds? | global winds are a combination of convection cells found at every 30 degrees of latitude |
| what does the name of a wind tell you? | the name tells me that it is a global winds and not a local winds |
| How much of the sun's energy actually reaches the Earth? | 50 % |
| what property are the layers of the atmosphere based on? | based on a mixture of gases |
| which calm area is located around 30 degrees north and south latitude? | trade winds |
| what is the atmosphere? | The atmosphere is a mixture of gases |
| List the 3 global winds and the 2 calm areas. | the global wind are trade winds, northern easterlies and westerlies the calm areas are doldrums and horse latitude |
| What is global warming? | global warming is a sudden heating in the air or area |
| If air mass increases what happens to density? | the density will increase |
| what type of winds blow over short distances? | doldrums and horse latitude |
| How are all winds created? | difference in air pressure |
