How land subsidence contributes to sea level rise
Earth.com staff writer
Today’s Video of the Day from NASA Goddard describes how land subsidence alters the shape of ocean basins and contributes to sea level rise.
During the last ice age about 20,000 years ago, the northeastern region of the United States, Canada, and other regions were weighed down by ice sheets. When the ice melted and its weight was lifted, the land surface slowly rebounded.
The resulting land movement, as well as subsidence related to human activities, play a significant role in sea level rise. For example, the Mississippi River Delta is essentially drowning as sinking ground is combined with higher sea levels, according to NASA.
