Explanation:
Welcome to Planet
Earth, the third planet from a
star named the
Sun. The
Earth is shaped like a
sphere and
composed mostly of rock.
Over 70 percent of the
Earth's surface is
water.
The planet has a relatively thin
atmosphere
composed mostly of
nitrogen and
oxygen.
Earth has a single large
Moon which is about 1/4 of its
diameter and, from the planet's surface,
is seen to have almost exactly the same angular size as the Sun.
With its abundance of liquid water, Earth
supports a large variety of
life
forms, including potentially intelligent species such as
dolphins and
humans.
Please enjoy your stay on Planet Earth.
