Why Study the Seafloor?

The ocean basins hold keys to understanding the two most important theories of geological science: plate tectonics and the sedimentary record of geologic history. Marine geologists and geophysicists were the first to discover the globe-encircling chain of volcanic mountains, called the mid-ocean ridge system, where new ocean floor is created.

Using their observations of the seafloor, these scientists developed the theory of plate tectonics, the idea that Earth's outer shell (lithosphere) is made of rigid pieces (plates) that move relative to one another over time. Plate tectonic theory explains the worldwide distribution of mountain ranges, ocean trenches (deep, arc-shaped valleys along the edges of the ocean basins), volcanoes, rock types, and earthquakes. By studying plate tectonics, scientists can better understand and predict geologic actions of today, such as volcanic activity and earthquakes. Scientists also know from studying plate tectonics that the moving...
