The geological changes of Greenland
Today’s Video of the Day from NASA Goddard provides insight into the geological history of Greenland.
NASA scientists have studied inconsistencies in Greenland’s crustal magnetic field to get a better understanding of the rate of heat flowing.
When the researchers investigated the Earth’s crust buried below the thick ice sheet, they found a thermal track recorded in bedrock that represents the movement of the North American tectonic plate. This discovery will help the experts better understand the movement of Greenland itself.
