What is the primary energy loss mechanism that converts tidal forces into Io's internal heat?

Answer

Tidal dissipation caused by internal friction between rock layers

The energy driving the process is orbital energy lost due to the friction generated as the moon deforms; this friction creates the thermal energy that generates magma.
