Recently, states on the east coast of the U.S. have been slowly sinking into the Atlantic Ocean due to flooding. The flooding isn’t always coming from the rainfall of the recent hurricanes Irma and Harvey, but even occurs on days you least expect it, sunny and calm days.

One of the possible factors of this occurrence could be that parts of Canada were covered by an ice sheet about 20,000 years ago during the last Ice Age. Due to the massive pressure, part of Earth’s mantle was pushed sideways under the ice, resulting in parts of the east coast the be raised. This problem was reversed when the ice sheet melted, ending in the coastal region
