Exam 9: Life on Jovian Moons

Compared to the moons of Jupiter, the moons of the more distant Jovian planets

Which of the following is the most convincing observation that suggests that like Europa, Ganymede may also have a subsurface ocean?

Triton's source of internal heat is mostly associated with

The possibility of life in a Europan ocean probably rests on the question of

Perhaps the MOST convincing piece of evidence suggesting that Europa has a subsurface ocean is the

If Europa turns out to have a subsurface ocean which is a 100 km deep or more, how much water would this correspond to, compared to the amount of water in the Earth's oceans?

If a future orbiter mission confirmed the existence of a subsurface oceans beneath Europa's icy surface, the next mission would most likely be

In addition to nitrogen, the other main components of Titan's atmosphere are

If Triton has a subsurface ocean, it will most likely consist of

What source of energy might keep water beneath the surface of Enceladus liquid?

Energy to support an origin of life in a Europan ocean would probably come from

Much of Europa's surface appears chaotic and clogged with huge iceberg-like blocks. This is consistent with

What is believed to have been the main source of Titan's atmosphere?

Which of the following is a moon of Neptune?

Which is the largest moon in the solar system?

What source of energy might keep an ocean beneath the surface of Ganymede liquid?

Io experiences strong internal tidal heating because of

Even though Titan has liquid methane on its surface, some internal heat, and plenty of carbon-containing compounds, it is not a suitable place for life because

Tidal friction between the Earth and the Moon causes

The complexity of any life present in Europa's subsurface ocean is mainly limited by the
