Our solar system is made up of planets, moons, asteroids,
comets, and a star. Earth is the only planet in our solar system
that can support life. It is in the perfect proximity to the sun, it
has water, and its atmosphere has the right gasses for us to
breathe.
Earth is found in the inner solar system, and is the largest of
the rocky planets. The Earth is 7,926 miles in diameter, and has a
circumference of 24,901 miles. Water makes up about 70% of
the Earth’‛s surface, while land makes up the other 30%. The
Earth rotates counter clockwise on its axis. Earth’‛s axis is tilted
at a 23.5 degree angle which is why we have seasons. Over the
course of one year, or 365 days, Earth makes one revolution
around the sun. Because the Earth is so dense, the gravity is just
right to keep us from floating away. Earth’‛s atmosphere allows us
to have weather and wind. Because of the moving tectonic plates
and weathering, erosion, and deposition, Earth has landforms,
volcanoes, and earthquakes. Our inactive volcanoes are known as
extinct volcanoes. At the poles, Earth has frozen water in
icebergs and glaciers.
The moon is Earth’‛s only natural satellite. It has a diameter
of 2159 miles and is much smaller than the Earth. It takes about
27.3 days to make one revolution around the Earth. The moon
does not have an atmosphere, so it also does not have weathering,
erosion, or deposition. This explains why the moon has so many
more craters than Earth. The ones on Earth’‛s surface have been
worn away over time. The moon does rotate on its axis and has
hills and extinct volcanoes. The moon is also made up of rock and
has frozen water, but no liquid water.
The sun is a star at the center of our solar system. Its
gravity holds the planets in their orbit. The sun’‛s diameter is
about 110 times larger than the Earth’‛s. Temperatures on the sun
are extremely hot starting at 5500 degrees Celsius. The sun
rotates on its axis and follows an orbit around the galaxy. Gasses
and a metal core make up the sun’‛s layers. It provides us with the
warmth
and
solar energy
we need to survive.
