Where are the world's two largest ice sheets and why is NASA studying them?
The two largest ice sheets are in Greenland and Antarctica. Together, they contain 75% of the world’s fresh water. If all this ice melted back into the ocean it would raise sea level by over 75 meters. This would change Earth’s surface in a big way: large areas of the continents would be flooded! This is why Earth scientists use satellites to measure the ice levels on Greenland and Antarctica to see if they are growing or shrinking.
