Students explore the effects of ice sheets on global sea level using NASA data. Using the resources provided, students collaborate and communicate their findings in a jig-saw activity format.


Located in the Arctic near the North Pole, Greenland is covered by a massive ice sheet three times the size of Texas and a mile deep on average. Greenland is warming almost twice as fast as Antarctica, which is causing the ice to melt and raise global sea levels.


The Earth's system is characterized by the interaction of processes that take place on molecular (very small) and planetary (very large) spatial scales, as well as on short and long time scales. Scientific visualizations allow us to experience Earth processes at faster speeds, and on manageable smaller scales, facilitating data analysis and enhancing understanding. Explore the visualizations below to see the new benchmark map scientists can use to study the extent and speed of changes to the largest ice sheet in the world.

The Eyjabakkajökull Glacier is an outlet glacier of the Vatnajökull ice cap in Iceland that has been retreating since a major surge occurred in 1973. Students analyze these maps to identify the scale, rate of change, and volume affected by the glacier retreat.



The advance-and-retreat cycle of snow cover drastically changes the whiteness and brightness of Earth. Using these two 2017 maps created using NASA satellite data, have students review the seasonal differences of snow and ice extent.
