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 |
