How did Earth get its water? Earth & Planets
WebWhere the present-day Earth has oceans covering much of its surface, the early Earth was covered in a magma ocean - a layer of molten rock hundreds of miles deep melted by the energy released during the collision. Any water present would only exist as water vapor in the atmosphere. Web26 de jan. de 2024 · There are two theories: Theory 1: The major building blocks of the Earth contained water from the start. This water then accumulated at the surface of our planet (by “degassing” from the … The origin of water on Earth is the subject of a body of research in the fields of planetary science, astronomy, and astrobiology. Earth is unique among the rocky planets in the Solar System in having oceans of liquid water on its surface. Liquid water, which is necessary for life as we know it, continues to exist … Ver mais One factor in estimating when water appeared on Earth is that water is continually being lost to space.
