Tidal heating converts repeated gravitational deformation into internal heat.

supported

As a moon moves through an eccentric orbit, the planet's tidal force changes in strength and direction.

supported

Io's intense volcanism requires a major internal heat source, Europa's induced magnetic signature supports a global salty ocean, and Enceladus's south-polar heat flow and water-rich plumes demonstrate active internal heating.
