That means Europa is constantly stretching as it orbits Jupiter. Answer: It isn't. But if you were to try, you would find a frigid ice ball, orbiting a massive planet. DOC The greenhouse effect occurs because Europa : - ice covered surface with few impact craters - double-ridged surface features strongly suggest a subsurface ocean below Ganymede : - largest moon in the solar system - heavily cratered terrain adjacent to fairly smooth terrain Callisto : - entire surface appears heavily cratered and ancient - most distant from Jupiter of these four moons b. it does not have a solid surface. c. Geysers of liquid nitrogen are seen erupting from its surface. As gravitational pulls tug Europa this way and that, the friction from all this flexing creates internal heat.

Unlike Earth, however, Europa's ocean lies below a shell of ice probably 10 to 15 miles (15 to 25 kilometers) thick, and has an estimated depth of 40 to 100 miles (60 to 150 kilometers). It's believed that these cracks are caused by the flexing from Europa's tides. So, sometimes Europa is farther away from Jupiter and sometimes it is closer.
