The surface of the Earth is always changing. Some changes like earthquakes, volcanoes, floods, and landslides happen quickly and other changes, such as most erosional processes, happen slowly over time. It's often hard to see these changes from ground level. A much broader view is needed, and multiple views that provide a record of change over time are especially helpful. Earth shots shows you how satellite data are used to track these changes.
