First question: if you melted Europa's ice, would there be any land?
Second question (assuming the answer to the first question is no), how much water would you have to remove after that in order to get any land?
Another way of asking the question would be, what are the highest underwater volcanoes/mountains on Europa? I understand that currently it's about 10-15 miles of ice, and then 40-100 miles of ocean underneath that. So I'm guessing a lot of water would have to be removed to get the first islands but I'm having a lot of difficulty finding an answer online.
