Earth cont- Ozone Layer

• Ozone layer- layer in atmosphere contains high
  concentration of ozone (O3)
• 97-99 of the sun's high frequency, ultraviolet
  light, which is potentially damaging to life on
  Earth.

Earths Moon

• Natural satellite
• Covered with craters
• No atmosphere causing space rocks to smash it.
• No air and weak gravity
• When sun shines, moon gets very hot, and when sun
  doesnt shine, moon gets very cold!

5
Mercury

• Small and rocky
• Closest to the sun
• Completes the trip around the sun every 88 days.

6
Venus

• 2nd Planet from our sun
• Very similar to Earth, although doesnt have an
  ocean

  over hundreds of years.
• Dangerous atmosphere, containing of hydrogen and
  helium.

9
Saturn
