Question

31:

What is the best explanation for the presence of active volcanoes on the surface of Jupiter's Io?

Group of answer choices

Jupiter's gravity distorts it as it alternately moves closer to and farther away from Jupiter.

Friction between blocks of ice causes the interior to melt, resulting in escaping gases.

As material sinks toward the core, the release of energy melts material, which then escapes as gases and molten rock.

Radioactive material heats up the satellite's interior, and molten lava escapes to the surface.
