| Question | Answer |
|---|---|
| describe the thermosphere | the hottest, outermost layer of the atmosophere |
| what is the atmosphere | multiple layers in the air |
| what kind of ways have humans polluted | car exhaust and fossil fuels |
| what is the ozone layer, where is it found | it is the layer that protects us from UV rays, in the stratosphere |
| describe jetstreams | fast moving air in our atmosphere |
| what is global warming | heat trapped in the earth, below atmosphere, that heats the earth |
| describe air pressure | the force of air downwards |
| what is smog | smog is a type of secondary pollution |
| our ozone layer absorbs which type of harmful radiation from the sun | UV Rays |
| what are auroras and where were are they found | found- ionisphere. Auroras are northern lights that light up most of the northern sky. |
| what happens to air pressure as altitude increases | air pressure decreases |
| what is the greenhouse effect | the greenhouse effect is warming in the atmosphere |
| what is the most common atmospheric gas | ozone |
| what part of the earth cools off faster and heats up faster? what does this unequal heating create | the Earth's surface. A change in the Earth's temperature |
| what are global winds | global winds are horizontal winds that move water |
| explain the three ways heat is transferred | Radiation Conduction Convection |
| what is the ozone layer? where is it found | the ozone layer is a gas in the atmosphere that protects us from UV rays. It is found at the stratosphere. |
| describe doldrums | located close to the equator. Trade winds found here |
| list the examples of local winds | mountain and sea breezes |
| how much oxygen and carbon dioxide are found in our air | |
| what is another name for the distance above sea level | wave height |
| what is significant about the troposphere | it is the layer of the atmosphere we live in |
| if air mass increases, what happens to density | density increases also |
| what are the two most abundant gases found in the atmosphere | nitrogen and oxygen |
| what is the name of a wind tell you | it blows fast |
| describe the movement of convection currents | convection currets give warmth to a object by touching it |
| list the three global winds and the two calm winds | polar easterlies, prevailing westerlies, and trade winds. Doldrums and horse latitude |
| which calm area is around 30 degrees north and south latitude | horse latitude |
| what types of winds blow over short distances | local winds |
| how are winds created | weather |
| how much of the suns energy actually reaches the earth | half a billionth |
| which global winds blow away from the poles to the west | polar westerlies |
| where do trade winds flow toward | from the south to the equator |
| what does the coriolis effect make the winds do | bend to the right of their motion |
| how much oxygen and carbon dioxide is found in our air | oxygen=21% carbon=1% |
| which instrument measures air pressure | barometer |
| what property are the layers of the atmosphere based on | density and latitude |
