Where did the water come from in Antarctica?

[QUOTE="Baluncore, post: 6242050, member: 447632"] It does not really work that way. Earth's thin crust floats on the fluid mantle. One effect is that when sea level is raised 4 metres, the added weight of water on the sea floor would push that down by about one metre, leaving a 3 metre difference on the coast. But pushing the oceans down lifts the land, which gives back more than a metre because there is more area of sea than land, so it lifts the mountains slightly. That is called isostasy. The real problem is finding something solid to measure sea level against. [URL unfurl="true"]https://en.wikipedia.org/wiki/Isostasy#Isostatic_effects_of_ice_sheets[/URL] [/QUOTE]
