This document discusses bathymetric maps and plate tectonics. It begins by asking key questions about bathymetric maps and plate tectonics. It then defines a bathymetric map as a map that shows what the ocean floor would look like if all the water drained out. It discusses using bathymetric data to understand plate tectonics. The document outlines identifying and labeling the seven major tectonic plates on a provided bathymetric map, determining their directions of motion, and moving the plates to model what Earth's surface may look like in 50 million years.
