This mini-lesson features time-series graphs of mean salinity at the surface for the Arctic and Antarctic regions. A series of questions guides students in their analysis.
Review this page to learn about the background of volcanoes and their eruptions.
Students examine satellite images of a recently formed island to identify areas of erosion and deposition.
Phytoplankton distribution background information.
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.
Watch NASA videos about aerosols and volcanic ash.
Students watch a video explaining albedo and its impact on Earth. The video shows visualizations of albedo across Earth and how it can change. Students will interpret the images in the video and answer questions about albedo.
Students analyze the stability and change of sea level after watching a visualization of sea level height around the world.
Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.
