TIDAL HEATING
Tidal heating is the heating of a planet or satellite due to the friction caused by tides.
Tidal heating
Tidal heating occurs through the tidal friction processes explained above: excess orbital and rotational energy are dissipated as heat in the crust of the moons and planets involved.
This flexing causes tidal heating of the three moons' cores. This is seen most dramatically in Io's extraordinary volcanic activity, and to a somewhat less dramatic extent in the geologically young surface of Europa indicating recent resurfacing.
Voyager 1 identified nine currently active (erupting) volcanoes on Io, probably driven by tidal heating. Many more are suspected. Voyager 2 observed eight of the nine; the largest shut down by the time Voyager 2 arrived at Jupiter.
The tidal heating from Jupiter has driven away much of the volatile materials like water, carbon dioxide, etc. Io's surface is a splotchy mixture of orange, yellow, black, red, and white.
Most important, some of the ice below may have been melted by radioactive decay and tidal heating from gravitational interactions with Jupiter to create a deep ocean of electrically conductive liquid such as salty water that generates fluctuations ...
This is what you would expect since there are fewer tidal forces and less tidal heating due to its greater distance from Jupiter. One surprising result from the Galileo spacecraft is the possible presence of a thin, salty ocean under the icy surface.
Ian Garrick-Bethell, also of UCSC but a proponent of the tidal heating theory, likes the new idea but thinks "more work should be done to understand if the observed topography, crustal thickness, ...
Though small compared to the tidal heating, this current may carry more than 1 trillion watts. It also strips some material away from Io which forms a torus of intense radiation around Jupiter.
It is not clear why Miranda has been so active geologically. Some theories invoke tidal heating effects earlier in its history, or a collision that tore it apart and allowed it to coelesce again. None are very conclusive.
diameter and yet shows incredibly complex jumbled geological structures with faults that appear to be global in size with surface features kilometres deep. These must have been formed in a violent stage in Miranda's life, either due to tidal heating ...
may be warmed to a liquid state by volcanic vents on the ocean floor (an especially intriguing theory considering the various types of extremophiles that live near Earth's volcanic vents), but the primary source of heat is probably tidal heating.
