THE ATMOSPHERE

THE ATMOSPHERE

1. Its composition

   • NITROGEN(72%)
     • cannot be used by living beings
   • TROPOSPHERE
     • weather processes
     • organisms
   • STRATOSPHERE
     • home to the ozone layer
     • temperature increases(altitude
   • MESOSPHERE
     • Shooting stars
     • meteorites falling
   • THERMOSPHERE
     • aurora borealis
   • .EXOSPHERE
   • OXYGEN(21%)
     • respiration
   • CO2(0.03%)
     • photosynthesis
   • WATER VAPOUR( 0.93%)
     • clouds and precipitation
   • NOBLE GASES
     • argon,neon,helium,krypton
   • HYDROGEN
   • OZONE

2. PROTECTS US...

   • solar radiation
     • ultraviolte
     • X-rays
   • meteorites

3. VITAL GASES

   • CO2
   • O2

4. REGULATION IN TEMPERATURE

   • Amount of solar radiation
   • greenhouse effect
   • gases escape others are mantained
   • 15ºC

5. Air pollutitants

   • gases
   • particulates
   • Light and noise

6. Effects

   • Acid rains
   • Deplation of ozone layer
   • Enhaancement of the greenhouse effect

7. PREVENT AIR POLLUTION

   • renewable
   • using energy rationally and efficiently
   • controlling industrial gas emissions
   • planting more trees
