Title: Sun Controls Earth


1
Sun Controls Earths Climate System
2
Earths Climate System
  • Earth has a global climate system that includes
    air, land, liquid water, ice, and living things.
  • The climate system is powered by energy from the
    Sun.
  • The Sun emits different types of radiation
  • ultraviolet radiation
  • visible light
  • infrared radiation

3
Earth Absorbs Suns Energy
  • When radiation strikes a particle, it can
  • get absorbed by the particle, causing particle to
    gain energy
  • be transmitted through the particle
  • be reflected off the particle
  • Suns Radiation
  • 30 is reflected back to space by clouds and
    surface of Earth
  • 70 is absorbed by surface, clouds and atmosphere

4
Earths Energy Balance
5
Balance of Energy on Earth
  • when Earths surface warms, it emits radiation
    back
  • the amount of energy Earths system absorbs from
    the Sun equals the amount of energy radiated by
    Earths system
  • therefore, Earths global temperature stays
    balanced
