eventually heat up‚ and the temperatures rise further. An ice sheet contains massive quantities of frozen water. The two ice sheets on Earth today cover most of Greenland and Antarctica. Ice sheets are made up of layers of snow and ice that collected over millions of years. If the Greenland Ice Sheet melted‚ scientists assume to estimate that sea level would rise about six meters (20 feet). For instance‚ if the Antarctic ice sheet melted‚ sea level would rise by about sixty meters (200 feet).
