Arches National Park Geology Tour provides an extensive, visually rich description of the geology of Arches, by Deborah Ragland, Ph.D. See our DVD collection.
This image shows the topography, or shape, of the Earth's surface, on land and below the oceans. Mountain ranges, subduction trenches, tectonic plates, and mid-ocean ridges are all visible in the image.

Surface Features of the Earth

This image of the surface of the Earth shows the North and South American continents, as well as the floor of the Pacific Ocean. As can be seen in the image, the ocean floor shows evidence of

The continental regions show evidence of

(Click on the image to see labeled examples of these features.)

These things provide evidence that, unlike other planets, the surface of the Earth is in motion. Motion of the Earth's surface is called plate tectonics.

Compare this active surface with that of Venus, Mars, or Europa.
