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.
Students will explore albedo, sea ice and the relationship between changing albedo and changing sea ice.
Introduction to the concept of albedo.
