Hi, Stevebd1. Hypothetically, would some of the melted ice evaporate to form clouds (provided that there were enough oxygen traped under the surface), reducing the sea’s volume? It has silicate rock under there somewhere. Do we know that there aren’t rock formations relatively close to the surface of the ice crust i.e. did Galileo’s data include all of Ganymede's surface area, or did it miss some when it passed? Thanks.
