
The seasons depend
on which side of
Earth is tilted toward
the sun.
 When the Northern
Hemisphere is tilted
toward the sun it is
summer in the north and
winter in the south and
vice versa.
Day vs. Night

During the summer the
number of hours of
daylight is longer and
the number of hours of
darkness is shorter.
•During the winter it
is just the opposite.
Longer nights and
shorter days.

The Inner Planets
Why they are called the “Inner Planets”
The inner planets are the four planets that lie between
the Sun and the asteroid belt.
Mars
Earth
Venus
Mercury
The planets that are located after the
asteroid belt are called the outer planets.
That makes sense, doesn’t it?
Characteristics of the Inner
Planets
• Closest to the Sun
• Composed mostly of solid rock
• Each have a core, a mantle, and a crust
• Many craters of varying sizes
• Sometimes called the “terrestrial planets”,
because of their similarities to Earth
• Smaller than most of the outer planets

THE OUTER PLANETS
The Outer Planets
The Big Gas Giants
Write Outer Planets
characteristics

The outer planets are Jupiter, Saturn,
Uranus and Neptune.

They are called the gas giants because
they have so much mass compared to the
terrestrial planets, and because of that
great mass, creating a stronger gravity
pull, forbids the gases from escaping ,
forming deep atmospheres of gases.
T Write he Outer
Planets
characteristics



The composition of their atmosphere is
similar to that of the Sun.
They are about 75% hydrogen, 24% helium,
and 1% other elements.
None of the giant planets have a solid
surface. The deeper the atmosphere the
denser it gets.
Jupiter
facts:




Jupiter is the 5th planet from the Sun.
It is the largest planet in the solar
system.
Jupiter’s diameter is 11 times that of
Earth’s
Jupiter is also 300 times as massive as
Earth.
Jupiter
facts

Jupiter has about 17 moons. One of the
moons called, Io is covered with
volcanoes.
Jupiter’s
atmosphere



Thick atmosphere made up of mainly
hydrogen and helium.
It contains colorful bands and swirls of
thick clouds.
Jupiter has a “Great Red Spot”, which a
giant area of swirling clouds. It appears
to be an on-going hurricane like on Earth.
Saturn’s facts



Saturn is the 6th planet from the Sun.
This is the second largest planet in the
solar system.
Saturn has beautiful rings that are
visible from Earth. These rings are made
up of chunks of rock and ice, each
traveling in its own orbit around
Saturn.
Saturn facts
Saturn has moons. Its
largest moon is called Titan.
It is larger than Earth’s
moon.
Saturn’s
atmosphere



Like Jupiter, Saturn’s atmosphere is made
up of mainly hydrogen and helium.
Its atmosphere is contains clouds and
storms but not as dramatic as Jupiter.
Saturn is the only planet that is less
dense than water. That means if we put
Saturn in water, it would float!
Uranus facts





Uranus is the 7th planet from the Sun.
It is four times the diameter of Earth.
Uranus is twice as far from the Sun as
Saturn, so it is much colder.
Uranus also has moons.
Uranus is tilted about 90o, therefore
rotating from top to bottom, while the
other planets rotate from side to side.
Uranus’
atmosphere


Like the other outer planets, it
atmosphere is mainly hydrogen and
helium
Uranus also looks bluish because of the
traces of methane that is also found in
Uranus’ atmosphere.
Neptune facts



Neptune is the 8th planet from the Sun.
Discovered by a mathematical
prediction.
Neptune also has moons.
Neptune
Neptune is the 8th planet.

Moon Phases
The shadow on the moon always disappears from
right to left when the moon is growing. If you can
see the right side of the moon, then it is growing.
The moon always disappear from left to right as
well. So if you can see the left side then it is getting
smaller.
