Question

Outer Planet Moons Answer any combination of parts that totals to 8 points. This is a work-ahead problem before we cover Jovian moons in lecture; see Chapter 11 of the textbook. Why do we think that Jupiter's moon Europa has an ocean? Io is the most volcanically active object in the solar system, and is relatively small. But let's find out whether it is shrinking noticeably over time. Calculate the fraction of Io's current mass that it will it lose in -4.5 billion years due to volcanism. Assume that Io's current mass is ~9 times 10^22 kg, and that it loses ~1000 kg of sulfur dioxide each second to space. Is Io shrinking significantly due to volcanic activity? Using Appendix E, which medium-sized moon of Saturn is in a 2:1 resonance with Enceladus? Why might this resonance be important for Enceladus? List two ways that Titan and Earth are similar. List two ways that they are different. Why do we think that Triton is a captured moon?

Explanation / Answer

4) earth and Titan are only two cosmic bodies have lakes and seas in whole solar system.

Titan also has polar wind's like earth, which pull gases from the atmosphere toward outer space.

Like earth the primary composition is nitrogen but unlike the esrth, one of the most abundant constituents methane.

Seasonal changes are different.

a)by the use of magnetic survey data, induced magnetic fields are arised, this suggests large conductive body( salty water) below surface. And large fratures and ridges are found like earth, this suggests plate tectonics due to flow of liquid.
