WebToday, the Earth’s surface is about 30% land and 70% ocean. On early Earth, the amount of land would have been less. Once the Earth had cooled enough to allow for liquid water to accumulate on the surface, that surface would have been covered by a global ocean, with a few volcanic islands peeking through (source: New Scientist). 2.
