Earth



Earth has a rocky surface as a planet
and also has water on it.
It has an atmosphere of gases around
it.
It orbits millions of miles from the Sun
as the third planet in the solar system.
Moon



The Moon is the natural satellite that
orbits the Earth.
It has a rocky, dusty surface with many
craters and no water.
It has no atmosphere.
Sun




The Sun is a star, a large ball of glowing
gases that is extremely hot.
It does not have a rocky surface and its
atmosphere glows and gives off light.
It is located at the center of the solar system.
Earth and other planets revolve around it.
How does the sun affect Earth?



Earth receives the heat and light after they
travel through space.
The Sun is the source of almost all energy on
Earth. Plants take the Sun’s energy and use it
to make food energy.
The Sun’s energy is stored in fossil fuels (for
example, coal, oil, or natural gas) that formed
from some organisms that died long ago.
How does the sun affect Earth?


The Sun’s energy causes weather
conditions on Earth.
Heat from the Sun causes the process
of evaporation of water on Earth’s
surface.
Earth’s Rotation

4-3.5
Explain how the rotation of
Earth results in day and night.
Rotation


Earth rotates (spins) on its axis
Earth completes one rotation in about
24 hours (23 hours and 56 minutes).

Earth rotates from west to east,
therefore, the Sun appears to rise in the
east and set in the west.


If you are on the east coast, you see the
sunrise over the water.
If you are on the west coast, you see the
sunset over the water.

Because of this rotation, only the side
of Earth facing the Sun is lit and
therefore experiences day; the side of
Earth not facing the Sun experiences
night.
