In other places, the surface of the Earth is covered with characteristic vegetation, such as the grasslands shown here. Or the surface might be frozen into a mushy wasteland such as the tundra of Alaska or Siberia.
This tour has shown you continents, plates, the depth of the crust, and a hint of what exists underneath. We have shown you oceans, ocean currents, rivers, and lakes. We have also shown you deserts and forests. We hope you have enjoyed this Exploratour of the Surface of the Earth.
