What does it mean for a planet to deemed habitable?
It can sustain life
100
An area around a sun in which the temperature allows for liquid water to exist on a planet's surface
The Habitable zone/ Goldilocks' Zone
100
Does Earth's temperature allow for life to exist?
Why?
Yes, allows for liquid water
100
What happens to water if the sun is too far? What about too close?
Too Close- evaporates away
Too Far- freezes
200
Why is Proximity to a planet important?
Controls temperature of a planet and whether or not water is liquid
200
Layer of gas
Held in place by gravity
Surrounds a planet
Atmosphere
200
Without our atmosphere, what consequences would we face?
Bonus points if you can name 3
!. Unable to breath
2. Loss of Heat
3. Nothing to stop the UV Radiation (cancer, whoo!)
200
True or false- A planet needs all three of these characteristics to sustain life- A gaseous atmosphere, Liquid water, and the correct proximity to its sun
True
300
This area around the sun is a section that allows for liquid water to exist and is one of the main characteristics habitable planets share. Proximity to the sun is the main factor here.
Habitable Zone/ Goldilocks' Zone

Moon
Ozone that protects from UV Radiation
Moon- not necessary for life
300
A hole in the ozone layer would result in what?
More UltraViolet radiation that could damage life
400
Why are Greenhouse gases needed?
They keep in heat/ thermal energy in the atmosphere
400
Found in Earth’s atmosphere

What are 3 things that Earth has that the other planets in our solar system do not have?
Life, a substantial amount of Oxygen, and Liquid Water
400
Name 2 things that allows the Earth to be inhabited, that Venus and Mars do not have
Not in habitable zone (Goldilocks' zone), no liquid water, not enough oxygen, temperatures on Mars and Venus are either too hot or too cold
