This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape. Data collected from satellites, such as the joint NASA/USGS Landsat satellites, help improve our understanding of Earth’s land cover. Orbiting Earth, these satellites monitor changes to land cover to help scientists predict changes due to runoff and erosion, and plan for the future.
The movement of water over a landscape is a constant force of change.
- Different types of land cover interact with water moving over the landscape in different ways.
- NASA scientists use observations from Earth and space to monitor changes and make predictions about the future of our planet.
