Atmosphere Vocab.

Ozone gas formed by a third oxygen atom to oxygen molecule exists in layer in the atmosphere and absorbs ultraviolet radiation from sun the major chemical is smog
Troposphere layer of atmosphere closest to Earth's surface where most of mass of atmosphere is found,this layer also is where most weather takes placed and air pollution collects
Stratosphere layer of Earth's atmosphere that's located above tropopause it's made up primarily of concentrated ozone
Mesosphere layer o Earth's atmosphere above stratosphere
Thermosphere layer of Earth's atmosphere that' s located above mesopause and contains only minute portion of atmosphere's mass
Exosphere Outermost layer of Earth's atmosphere that's located above thermosphere and contains light gases like helium and hydrogen
Radiation energy transfer through space by visible light,ultraviolet radiation and other electromagnetic waves
Conduction energy transfer that occurs when molecules collide this takes place ONLY when substances are in contact with each other
Convection transfer of energy by flow of heated substance
Temperature measurement of speed of the molecules
Heat energy transfer that occurs because of difference in the temperature between substances and flows from object of higher temperature to object of low temperature
Dew Point temperature which air is cooled at constant pressure to reach saturation at which some point condensation can happen
Condensation process by which cooling gas changes into liquid and releases thermal energy it changes matter from gas to liquid
Lifted Condensation Level height at which condensation occurs it often corresponds with base of clouds
Temperature Inversion increase in temperature with height in atmospheric level which inverts temperature-altitude relationship this can worsen air pollution problems
Humidity amount of water vapor in air
Relative Humidity ratio of water vapor contained in specific volume of air compared with how much water vapor that amount of air actually can hold
Condensation Nuclei small particles in atmosphere around which cloud droplets can form
Orographic Lifting cloud formation that occurs when warm moist air is forced to rise up side of mountain
Stability ability of air mass to resist rising
Latent Heat stored energy in water vapor that's not released to warm atmosphere until condensation takes place
Coalescence process that occurs when cloud droplets collide and form larger droplets which eventually become too heavy to remain aloft and can fall to Earth as rain
Precipation all solid and liquid forms of water that falls from clouds like rain,snow,sleet, hail
Water Cycle continual movement of water between Earth's surface and atmosphere through evaporation,condensation,precipation
Evaporation vaporization is a change of stat involving thermal energy evaporation is a process by which water changes from liquid to gas
