weather test part 1
| Question | Answer |
|---|---|
| 4 main factors of weather | humidity, wind, temperature, and air pressure |
| how are the four factors connected | as temperature increases humidity increases, as air pressure changes wind is created, and as air pressure changes humidity changes |
| what are the three forms of heat | radiation, conduction, and convecation |
| give an example of the three types of heat | radiation- heat from the sun conduction- the sun warming the ground which warms the air convection- warm air rises and cold air sinks |
| name the layers of the atmosphere | troposphere, stratosphere, mesosphere, ionosphere, thermosphere, and exosphere |
| what happens in the toposphere | weather |
| what happens is the statosphere | air travel |
| what happens in the mesosphere | stops meteors |
| what happens in the ionosphere | auroras |
| what happens in the thermosphere | traps heat |
| what happens in the exosphere | satilites to and unlimited height |
| compare how air pressure changes with altitude | air pressure decrease altitude increases, as air pressure increases altitude decreases |
| what is an isobar | an imaginary line that connects similar air pressures |
| how is wind created | different air pressures in the atmosphere |
| what happen with high pressure | fair. clear, sunny weather; wind spins to the right; barometer # will be high because air is more dense |
| what happens with low pressure | cloudy, rainy weather; wind spins to the left; barometer # will be low because air is less dense |
| land breeze | ool air from the land rushes out ot the sea. It warms up and rises back into the atmosphere and heads towards the land. |
| sea breeze | cool air from the sea rushes towards the land. it warms up and rises back into the atmosphere and heads towarss the sea. |
| wind measured with | anemometer |
| temperature measured with | thermometer |
| air pressure measured with | barometers |
| moisture/ humidity measured with | psychrometer |
| trade winds | blow from the horse latitudes to the equator |
| horse latitudes | are calm areas of falling air |
| prevailing westerlies | blow away from the horse latitudes towards the poles |
| duldrums | calm areas where warm air rises |
| coriolis effect | the earths rotation from west to east underneath the wind makes winds curve instead of blowing in a stright line |
| polar easterlies | blow from the east to the west |
