   When air is heated it becomes less dense as a result lighter  It rises upward above the cool air  Air expands because there’s less amount of pressure higher up in the atmosphere https://www.meted.ucar.edu/sign_in.p hp?go_back_to=http%253A%252F%252 Fwww.meted.ucar.edu%252Ffire%252Fs 290%252Funit6%252Fprint.htm

   It means a topographic uplift and forced land lifting  When this type of lifting happens the land forces the air to move to a higher elevation  The temperature of the air cools as is it is lifted up higher in the atmospher http://www.waterencyclopedia.com/Ce-Cr/Climate-Moderator-Water-as- a.html

   When warm air and cool air collide  Warm air is less dense then cooler air so it’s wedged upward.  This ends up causing fronts that usually means rain.
• 5.
   Whenever air in the lower atmosphere flows together, lifting results  Air flows in different directions, it has to go somewhere so it goes up  It can lead to adiabatic cooling and cloud formation http://10.85.0.4:8080/ibreports/ibp/b p.html?fn=Students&fp=1&ip=10.182. 1.49&ibip=10.85.0.4&ldu=0&re=0&bu =www.islandnet.com/~see/weather/el ements/whatgoesup3.htm&bc

   Unequal heating of the Earth’s surface may cause pockets of air to be warmed more than the surrounding air  The pockets of air that get warmed more will become less dense than the surrounding air will move upward  These clouds might produce rain

   Stable air resists vertical movement  It won’t get warm, expand, and less dense and rise. But it also won’t cool and become more dense and sink http://ocw.usu.edu/Forest__Range__an d_Wildlife_Sciences/Wildland_Fire_Man agement_and_Planning/Unit_7__Atmos pheric_Stability_and_Instability_1.html

   It happens when water vapor in the air changes to a liquid  This may result in dew, fog and clouds  But for any of those above to happen the air has to be saturated, it occurs when air is cooled to a dew point. Less often when water vapor is added to the air http://shoalwater.nsw.gov.au /Education/condensation.htm

   Clouds are classified based on their form and height  Cirrus- the clouds are high, white and thin  Cumulus- clouds are rounded individual cloud masses  Stratus- best described as sheets of paper that cover much of the sky http://www.enchantedlearning.com/su bjects/astronomy/planets/earth/cloud s/

   The types of clouds in this category are cirrus, cirrostratus, and cirrocumulus  Cirrocumulus clouds are fluffy masses and cirrostratus are thin white layers  If a cirrus cloud are fallowed by a cirrocumulus or cirrostratus cloud they may warn of stormy weather http://www.srh.noaa.gov/key/?n=high _clouds

   They range from 2000 to 6000 meters in the air  Altocumulus clouds are rounded masses but Cirrocumulus clouds are larger and denser  Covers the sky may mean a light snow or drizzle may come http://www.beijinghikers.com/v2/reso urces/news/hiking-photos- switchback-great-wall-2009-12-16/

   Consists of stratus, stratocumulus, and nimbostratus clouds  It is a fog like cloud that covers most of the sky and occasionally might show light precipitation  Nimbostratus clouds form the most precipitation and form from air being forced upward http://chr.wikipedia.org/wiki/ File:Low_clouds.jpg

   Some clouds do not fit in the three categories  some clouds have bases in the low height range but often extend into the middle or high range  Cumulus clouds with air flowing upward would develop rapidly http://www.uwgb.edu/dutchs/EarthSC 102Notes/102Clouds.htm

   Clouds and fog are basically the same except the place formation fogs just a lot lower  Cause by Cooling- a blanket of fog is produced with warm moist air  Caused by Evaporation- when cool air moves over warm water it often evaporates and makes fog http://www.brainharmonycenter.com/ brain-fog.html

   Bergeron process relies on to physical processes: super cooling and super saturation  The temperature in the air needs to be sometimes -40 degrees Celsius but under 0 degrees Celsius is considered super cooled  It would have to be 100% relative humidity but supersaturated is more than 100% humidity http://nanopatentsandinnovations.blo gspot.com/2010/06/amount-of-dust- pollen-matters-for-cloud.html

   The mechanism for this is collision- coalescence process  Some water absorbing-particles can remove water vapor and form drops that are large  As they move through the cloud they collide and join together with smaller slower droplets http://rst.gsfc.nasa.gov/Sect14/Sect14 _1d.html

   Rain means drops of water that fall from a cloud and have a diameter of at least .5 mm.  When the temperature is above 4 degrees Celsius the snowflakes continue decent as rain  At temperatures are above -5 degrees Celsius they clump together and make snow flakes http://itunes.apple.com/us/app/snow /id287063264?mt=8

   Sleet is the fall of small particles of clear-to- translucent ice  Hail is produced in cumulonimbus clouds they begin as small ice pellets  Each trip through a super cooled cloud just adds a layer of ice
