Water trapped in dust grains from which the Earth formed can explain the current large amount of water on Earth.

This is suggested by scientists from the Netherlands, Germany and the United Kingdom, based on calculations and simulations. The research will appear in two articles in the journal Astronomy & Astrophysics.

Time - Scientists - Explanation - Amount - Water

For a long time scientists have struggled with an explanation for the large amount of water on Earth. A first scenario states that the water is delivered by comets and asteroids that hit the Earth. According to a second scenario, the Earth was born 'wet' and the water was already present on ten-kilometer-big boulders from which the Earth was built up. However, the amount of water that these large boulders can contain is limited.

Now, an international team of scientists has devised and calculated...
