ROLE OF WATER

Water on Earth
- Large bodies of water on Earth are hypothesized to have originated from asteroids
- These asteroids formed at a distance from the Sun where the cooler temperatures would have allowed the water to be frozen as ice
- When the asteroids collided with Earth, the planet had achieved sufficient mass (and gravity) to retain the water and had cooled enough for it to condense
