Sea and Land Ice Melt

Arctic sea ice is the cap of frozen seawater blanketing most of the Arctic Ocean and neighboring seas in wintertime. It follows seasonal patterns of thickening and melting. Students view how the quantity has changed from 1979 through 2018. 

Students examine the two time series images to determine the differences between seasonal ice melt over water versus land.

Students will watch a video on the Greenland Ice Sheet and answer questions.

Students watch the video Frozen Earth and answer the following questions that discuss how ice helps moderate the planet's temperature using NASA satellites.
