$100 Question Ch11
Why are there no impacts in the surface of Io?
A)
It is too small to have been bombarded by
planetesimals
B)
Jupiter s strong gravity attracted planetesimals
more strongly than Io and thus it didn t get impacts
C)
Io had impact craters, but they have been
buried by lava flows
D)
Any craters that existed have been eroded
through strong winds in Io s surface

$400 Question Ch11
Why do the jovian planet interiors differ
A)
The more distant planets formed in a cooler region
of the solar nebula and contain as much hydrogen but greater
proportion of ices
B)
They differ due to giant impacts at the late stages of
planet formation
C)
The closer planets formed their cores first and
captured more of the gasses
D)
The more distant planets had longer to form since
the solar nebula lasted longer at greater distances from the Sun

$500 Question Ch11
Why does Jupiter have several distinct layers?
A)
Clouds form randomly so on average there are
always several layers
B)
Different layers represent different regions where
the temperature is cool enough for water to condense
C)
Different layers represent clouds made of gases
that condense at different temperatures
D)
Winds prevent clouds from forming at some
altitudes, so we see only clouds at the other altitudes
E)
Different gases are present at different altitudes in
Jupiter’s atmosphere
