BYU GEOLOGY 109 EXAM 3 QUESTIONS & ANSWERS
Jupiter is different from the terrestrial planets in what important way? - Answer -It
radiates more energy than it receives from the Sun.
The banding of Jupiter's atmosphere is probably related to which of the following? -
Answer -Turbulent winds in the atmosphere of this rapidly spinning planet.
Jupiter is composed mainly of ____________. - Answer -hydrogen and helium
Why is Jupiter so much larger than all of the terrestrial planets combined? - Answer -It
formed in the outer solar system where water ice was stable.
Where does Jupiter's large magnetic field come from? - Answer -Convection in a layer
of ionized hydrogen may create the magnetic field.
What are some important characteristics of the atmosphere of Jupiter? (Select all that
apply.) - Answer -The clouds are made of ices of ammonia (NH3) and water.
Jupiter's atmosphere formed by trapping nebula gas on to a large icy core.
It is poor in carbon dioxide, unlike Mars.
In what way is Io similar to Earth's Moon? - Answer -They are about the same size.
They have about the same density.
Both are tidally locked with one face pointed toward their host planet.
The surface of Io is thought to be less than a million years old because
