CONDITIONS FOR LIFE

ENERGY

• The planet should have enough gravity for
• us to move on it.
• The suns light we need to keep us warm.
• The suns light is used also for us to make food
• and stay alive.

ATMOSPHERE

• It is made up of various gases
• ( primarily nitrogen, oxygen,etc.)
• It acts as a protective shield.
• The atmosphere is held to the earth
• by its gravity also it helps the temperature.

WATER & TEMPERATURE

• We have a very stable climate due to earths
• distance from the sun.
• Water is the most important chemical we need.
• Its unique because it comes in 3 forms liquid,gas,and solid.
• When it evaporates it effects temperature.

WHAT IS NECESSARY FOR LIFE & ROTATION

• They help support life by making it able for us to
• live because of earths cycle.
• Photosynthesis would be difficult on venus because
• half of the time venus is dark due to its period of rotation
• and how close it is to the sun.

WHAT 3 THINGS ARE NECESSARY FOR LIFE ON EARTH

• The three things that are necessary for life
• on earth are water, food, oxygen, and atmosphere.
• If we didn't have air(oxygen) we wouldn't be able to
• survive also we need a gravitational pull to hold us down
• so we don't fly off the ground.

• qualities yes. Also i like jupiter and saturn i think they just always
