More differences of #OceanWorld ice.

Temperature. At top of many icy moons, the ice is waaay colder than Earth. 100 K on many worlds. The coldest on Earth is maybe 200 K. Cold ice is different. Harder, abd high thermal conductivity makes it harder to melt at a spot on surface (heat energy just conducted away.)

Formation. Ice sheets and glaciers are meteoric ice. Comes from snowfall. On Ocean Worlds (except some areas Enceladus is freeze down ice.
