Explanation:
Water
(Dihydrogen Oxide, H2O) is a truly
remarkable chemical compound, fundamental
to life on Earth.
Earth is the only planet in the Solar System where
the present surface temperature
and pressure allow
the three forms of water, solid
(ice), liquid
(ocean),
and gas (water vapor condensing
in clouds)
to exist simultaneously.
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.
