Volcanic Theory of Water

Clip: Season 37 Episode 11 | 1m 58s

The origins of water on earth have long been debated. Recent evidence suggests that water was always here, trapped beneath the crust. Volcanoes acted like a tear in the surface of our planet allowing the water to slowly escape as vapor. This condensed in our atmosphere and fell as rain, which eventually turned the planet from barren to blue.
