Space Math/Science challenge 1

In order for life as we know it to exist, a planet must have ______________________

• heat
• animals
• liquid water
• solar energy

Earth’s atmosphere contains water vapor and carbon dioxide. These greenhouse gases are important because they -

• are substances animals need to breathe.
• trap thermal energy in the atmosphere.
• 
  protect against magnetic particles.
• create Earth’s gravitational field.

The Goldilocks Zone is determined by the

• mass and brightness of the planet

• mass of the planet

• mass and temperture of the star

• gravity of the star

According to the lesson , what three things are needed for life to exist?

• A liquid medium for chemical reactions to take place (water)

• The basic building blocks for life CHONSP

• An energy source of some type (solar, thermal...)

• bread, water, and oxygen

What is the habitable zone?

• A zone with the correct distance away from a star
• A zone in space where water turns into vapor
• A zone where life can not be sustained
• A zone in space where water is frozen
