Explanation:
Water (Dihydrogen Oxide, H2O) is a truly
remarkable chemical compound and is fundamental to life on
Earth.
Earth is the only planet in the
Solar System where
the surface temperature and pressure allow
the three forms of water, solid (ice),
liquid (ocean),
and gas (water vapor condensing in clouds)
to exist simultaneously on its surface.
Water in one of these forms accounts for everything visible
in this view of
Earth from space looking north
at the Bering Sea and the coast of
Alaska, USA, around Bristol Bay.
