2. It is the most volcanically active body in our solar system. 3. It is thought to have a deep, subsurface ocean of liquid water. 4. It is the largest moon in the solar system. 2. It is the most volcanically active body in our solar system. At least one eruption seems to be occurring at almost all time Which moon is considered likely to have a deep, subsurface ocean of liquid water? 1. Io 2. Miranda 3. Europa 4. Triton 3. Europa We cannot see tidal forces or tidal heating; rather, we predict that they must occur based on the orbital characteristics of the moons. What observational evidence confirms that tidal heating is important on Io? 1. active volcanoes on Io 2. Io's unusual, egg-like shape 3. Io's surprisingly elliptical orbit 4. the orbital resonance between Io, Europa, and Ganymede 1. active volcanoes on Io Without some ongoing source of internal heating, Io would be similarly inactive. Therefore, the fact that Io is the most volcanically active world in the solar system tells us that it must have an ongoing internal heat source, which we identify as tidal heating.

"Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
