Glaciers from the alst ice age melted. Britain was once connected to Europe by land and there was a Texas sized piece of land connecting Siberia with Alaska. The glaciers held a lot of water and when they metled, sea levels rose A LOT!.
when the rest of them melt
what are we looking at
I'm always confused by this. If water expands when it freezes, why wouldn't the sea levels lower when the polar ice melts? Is there enough ice on land to make the difference? Pardon my ignorance....
