the
Earth, Sun, and
Moon
BY SARAH MILLINGTON
SIZE
(The diameter)
• The sizes of the three planets are all different.
• The Moon’s size is 3,475km (you could fit 4 Moons in
the Earth).
• The Earth is much bigger than the Moon, its
diameter is 6,371km.
• The Sun is a lot larger than the Earth and Moon
combined it is,1.392 million km.
Gravity
• The Moon has six times less the gravity on Earth. It has
1.622 m/s 2.
• The Earth has 9.78m/s2.
• The Sun has the strongest gravity out of the Earth and
Moon. It has 274m/s2.
• Gravity also effects your weight. If you have less
gravity you have less weight.
Water
EARTH
o There is a ton of water on
Earth.
o In fact 70% of the Earths
surface is water.
MOON
o Water on the Moon has
always been questioned.
o Water has been discovered
on the Moon.
o There are tiny particles of
ice everywhere.
Revolving and Orbiting
The Earth rotates around the Sun. It takes 365
days (one year) for the Earth to do one full
spin around the Sun!
The Moon orbits the Earth. The Moon takes
291/2 days to orbit the Earth!
The Sun does not orbit anything! Galileo
proved it!
Weathering and Erosion
 Weathering is a
process where rock
is dissolved, worn
away, or broken
down into smaller
pieces.
 Erosion can be
caused by natural
elements such as
wind, rain, and
glacier ice.
• Because the Moon’s water
is frozen there is little to no
weathering.
• There is weathering and
erosion on the Earth!
• The Sun is what causes
weathering and erosion on
the Earth. The Sun’s heat
shines on the rocks on
Earth it expends and breaks
down.
Rotating on its Axis
• The Moon takes 27.322 days to rotate on its
axis.
• The Earth takes 24hrs (one day) to rotate on its
axis.
• The Sun takes 24.47 days to rotate on its axis.
Weather and Atmosphere
Moon
• The moon has no
atmosphere.
• The temperature range is
387*F- 253*F.
Earth
• The Earth does have an
atmosphere. It holds air on
our planet.
• Some types of weather is
snow, hail, sleet, rain, and
wind.
The Tides
Tides are the rise and fall of sea levels.
They are caused by the combination effects of
the gravitational forces exerted by the Moon,
the Sun, and the rotation of Earth.
What Causes the Seasons?
The tilt on the Earth’s axis causes the seasons.
When the Earths axis I pointed in different
directions it causes the different seasons!
