Claim

Juvenile water, the water added to oceans through volcanoes, hot springs, and other vents, is added to oceans at such a rate that the oceans could not be more than 320 million years old to be as full as they are now.

  1. Morbidelli et al. calculated the water content of the Earth's surface to about 0,05% earth masses. Enstatites, a kind of meteorites which are sometimes assumed to resemble surviving precursor material of the planet Mars, according to Morbidelli et al., also contain about 0.05% water. If Earth would have been formed by accretion of such material it could never have had more water in its interior than we can find today on its surface. However, due to hotter environment because Earth formed closer to the sun than Mars, its precursor material probably contained less water than enstatites. Also, it is possible that large amounts of water are lost during accretion and formation of the moon, if the impact theory for explaining the formation of the moon is correct. So it is not at all easy to to explain the large amount of surface water on earth by degassing from the interior. Therefore many scientists are convinced today that the amount of real juvenile water, delivered by volcanos from the interior of the earth, is too low to account for the large amount of water on Earth's surface. Therefore, they assume that the early earth got the water by the impact of comets or large water-rich asteroids.
  2. It is well-known among hydrometeorologists that the quantities of neither juvenile water nor connate water are appreciable in comparison to meteoric water, and that juvenile water is not a candidate for the origin of the oceans. This claim is contrary to fact.
  3. Even if it "just" took 320 my to fill the oceans up to their present levels, the Earth is still much older than YEC people claim to be.
