| Question | Answer |
|---|---|
| meteorologist | someone who studies the weather |
| barometer | measures differences in air pressure |
| thermometer | measures temperature in the troposphere |
| psychrometer | measures relative humidity |
| anemometer | measures wind speed |
| windvane | measures the direction wind is coming from |
| humidity | the amount of moisture in the air |
| high pressure | sunny, nice day, low humididty |
| low pressure | cloudy, stormy |
| precipitation | rain, snow, sleet, hail |
| cold front | symbol-arc with blue triangles all faceing one direction moves-quickly cold air moves in and pushes upwards under the warm air |
| warm front | symbol-arc with red semi circles all faceing one direction moves-slowly warm air moves in and pushes up and over cold air and causes showers, fog, and clouds |
| occluded front | symbol-arc with alternating red and blue semi circles and traingles weather is rainy, humid, oppressive warm air mass caught between two cold air masses |
| stationary front | two fronts collide and dont move, rainy symbol is red semi circles on one side and blue triangles on the other side |
| troposphere | where weather occurs |
| stratosphere | keeps oceans liquid and the UV rays out-ozone layer |
| mesosphere | meteoroids burn up and turn into meteors |
| thermosohere | hottest layer |
| exosphere | where satellites orbit |
| ionosphere | where northern lights occur-ions emitted by the sun |
| evaporation | the process of becoming a vapor (gas, mist) |
| condensation | water that collects as droplets on a clod surface come into contact with warm air |
| run-off | precipitation that falls to the ground and collects/empties into a body or water |
| solid water | very very slow if it moves at all |
| liquid water | medium speed |
| gas water | very fast molecules |
| radiation | the giving off of heat |
| conduction | transfer of heat |
| convection | heat by currents and the rising of hot and cold substances |
| nuclear energy | energy released in a neclear reaction |
| chemical energy | part of energy in a substance that csan be released be a chemical reaction |
| electrical energy | energy made available nbe the flow of electrical charge through a conductre |
| mechanical energy | energy in a mechanincal form |
| potential energy | when an object is not moving but has potential to |
| kinetic energy | when an object is moving because it has changed from potential |
| energy transformation | the process of changing one type of energy into another |
| reflection | when something reflects light |
| refraction | reflection of light that changes the direction of the wave length |
| absorption | when a dark color takes light in |
| transparent | see through clear |
| translucent | see through foggy |
| opaque | solid colr/doesnt reflect light |
| wavelength | length of one crest to another |
| electromagnetic spectrum | range of wave lengths |
