how did water appear in Earth and how did we end up with such vast amount of it?
In: Earth Science
Water is really common in the universe. It’s made of hydrogen (by far the most common element) and oxygen, which is made by stars and not very rare either. Water is found on/in all the gas giants, on many moons, and most/all objects out near pluto, in the Kuiper belt.
I don’t know if we do have a huge *amount* of it; some moons of Jupiter and Saturn have tons and tons of water ice. Mars had a huge amount of liquid water, but it’s all either frozen or swept away now that the planet has no magnetic field (along with its atmosphere). Venus probably lost whatever water it formed with to solar wind in the same way.
