This activity invites students to model and observe the effect of melting ice sheets (from land) on sea level and the difference between the effect of melting sea-ice to that of melting land ice on sea level.
Our Earth is a dynamic system with diverse subsystems that interact in complex ways. Questions that scientists have about the Earth as a System may include the following. As you learn more about the Earth System, reflect on these questions.
Students use albedo values of common surfaces along with photographic images of Earth taken from the International Space Station to make an argument about specific anthropogenic activities that impact Earth’s albedo.
