A tidal heating is also known as the tidal fluxing and occurs by the tidal friction that is a product of the orbital energy of the moon either on the surface or either under the surface. Hence the deformation of the body is due to the tidal bulge.
<u>A product of the gravitational energy and this is known to be responsive to the formation of the geologic activity. Lo moon and Europa and the Ganymede have the same mechanism that provides with the energy to melt the ice layer and thus all the body's radius, density, and rheological parameters are needs for the formation of this system.</u>
