- climate
- the average weather over a long period of time, usually centuries
- earth's first atmosphere
- hydrogen and helium, then no atmosphere
- factors of climate
- latitude, elevation, proximity to water, ocean currents, topography, prevailing winds, vegetation
- thermosphere
- low density top layer, where temp increases drastically
- elevation
- cooler at higher elevations
- proxmity to water
- coastal areas have smaller temp ranges
- ozone
- O3, protects us from harmful UV rays, when O3 is broken into oxygen and one O heat is released, hence global warming
- topography
- leeward side may be warmer, or windward
- mesosphere
- third layer, temperature drops
- photosynthesis
- light + CO2 + H20= C6 H12 O6 +O2
- ocean currents
- warn currents heat coastlines, cool currents, cool coastlines
- tropopause, stratopause, mesopause
- the layers between tropo,strato and meospheres respectively
- weather
- the day to day state of the atmosphere
- vegetation
- affects how much the earths surface absorbs or reflects heat
- latitude
- cooler towards poles
- stratosphere
- second layer, temp increases w/ altitude b/c of ozone, meteors burn up here
- troposphere
- lowest layer, all weather here, temperature drops with altitude
- prevailing winds
- winds determine if air masses arrive from hot or cool regions
- current atmosphere forming
- volocanic gassing, mainly water vapor, some CO2 and SO2 then an algae bloom
