Respuesta:
Water is an essential part of our planet. Without water, no life would
be possible. We all learned about the water formula and its cycle
in nature. We have also seen how much water there is in the oceans
on maps, but... do we know how water appeared on our planet?
One of the most known theories says that water appeared in our
planet because asteroids and comets have water in them in the form
of ice. In the Pre-Cambrian era, thousands of meteorites hit
the surface of Earth, causing great destruction. The water stayed
on our surface and helped create life.
Another theory claims that water existed on Earth from the beginning.
Scientists have discovered some asteroids as old as our planet and
found evidence of water in them. According to some experts, water
could have appeared before we even arrived.
