Why are the terrestrial planets
rocky and the jovian planets
gassy/icy?
Why are the terrestrial planets
rocky and the jovian planets rocky?
At the formation of the solar
System, the sun took
The atmosphere from the
Planets close to the sun.
Why are the terrestrial planets
hotter than the jovian planets?
Why are the terrestrial planets
hotter than the jovian planets?
Terrestrial planets are
Close to the sun so they are
Hot. Jovian planets are
Far from the sun so they
Are cold.

If the orbital speed for Venus and
Saturn is the same, which would
complete an orbit of the sun in less
time? Explain
If the orbital speed for Venus and
Saturn is the same, which would
complete an orbit of the sun in less
time? Explain Venus would
complete its orbit sooner than Saturn
because it has a shorter distance.
Is this a scale model of the solar
system? Explain
Is this a scale model of the solar
system? Explain No, the planets are
too close together.

No, no plate tectonics, no erosion
Which crater happened first, A or
B?
Which crater happened first, A or
B?
Impact
B was

What is an AU?
What is an AU? The distance from
the sun to Earth, 150 million km.
What is an AU?
Convert 0.5 AU into kilometers.
Convert 0.5 AU into kilometers.
Multiply 0.5 * 150,000,000
km = 75,000,000 km
Convert 450 million km into AU.
Convert 450 million km into AU.
Divide 450 million km by 150
million km = 3 AU
