Land Topography, Coastlines & Geologic History
Discover a website that shows the "ups and downs" of the land. Learn about our coastlines and "U.S. Geologic History."
  • See how elevation range varies within our states
  • Find out if Earth's deepest ocean is deeper than Mt. Everest is high
  • Why are map scales "key" for interpreting elevation data?
  • Investigate which forces can sculpt landforms over a "short" amount of geologic time
  • Learn that geologic processes have also shaped our coasts
  • Discover that the coastline is a balance between the slope of the shore and local water level
