The Earth is made up of about two-thirds water, and scientists have thrown around ideas for years about where all of this water may have come from.
Although the great debate is still in the air, many have thought that the Earth had received all of its water from comet impacts, but new research indicates that the water may have come from rocks in between the planets of Mars and Jupiter, which were supposed to form yet another rocky planet, which is better known as the asteroid belt.
As these rocks come crashing down on the surface of the Earth, the impact generates a lot of heat, which as demonstrated in the video above, can release all of the water that has been chemically bonded to the rock into the skies, allowing it to rain down on the Earth's soil.
Despite the fact that the amount of water from each rock may not have been a lot, considering the fact that the Earth is more than 4 billion years old, it has had quite a while to collect this water.
