Global Seafloor topography from Satellite Altimetry
Maps of seafloor elevation based on data collected by satellites. The satellite can't "see" the bottom of the ocean, instead it measures the elevation of the ocean and infers the shape of the seafloor. It seems like magic, but it's really science. See how cleverly it's done.

Distribution of major tectonic plates and their directions of motion
Rectangular map, each plate is a different color. Continental and oceanic areas are continguously colored.

The Paleogeographic Atlas Project
Site contains maps showing the distributions of tectonic plates over geologic time. Unlike other sites that only show changes in the position of the tectonic plates, the paleogeographic reconstructions here show changes in the distribution of oceans vs. land.
