The world's ocean is heated at the surface by the sun, and this heating is uneven for many reasons. Earth's rotation, revolution around the sun, and tilt all play a role, as do the wind-driven ocean surface currents.This animation shows the long-term average sea surface temperature, with red and yellow depicting warmer waters and blue depicting colder waters.
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. See how the quantity has changed from 1979 through 2018.
View this video to see the evolution of the SMAP sea surface salinity (SSS) and soil moisture responses to Hurricanes Harvey, Irma, and Maria of 2017.
The radar measurements made by NASA's Soil Moisture Active Passive (SMAP) observatory are sensitive to whether land surfaces are frozen or thawed. Students analyze two maps of SMAP data to make inferences about changes to the Arctic's Geosphere showing spring thaw.
Students will explore albedo, sea ice and the relationship between changing albedo and changing sea ice.
Students will use the NASA Earth Observations analysis tool to explore changing albedo in the Arctic compared with other areas of Earth.
An urban heat island is a phenomenon that is best described when a city experiences much warmer temperatures than in nearby rural areas. The sun’s heat and light reach the city and the country in the same way. The difference in temperature between urban and less-developed rural areas has to do with how well the surfaces in each environment absorb and hold heat.
Students observe the surface temperatures of a variety of surface types found in a suburban environment.
Teachers, are you looking for resources to help you engage students in data analysis related to changes in the cryosphere using albedo values? Check out this poster card set.
