Geology of the Ocean

By Katie Wallace & Sarah Turcotte

The study of the ocean floor is known as geological oceanography.

The theory of continental drift and the movement of the tectonic plates are also very important in

geological oceanography.

“Seafloor spreading is the theory that explains how the floors of oceans had split apart and rocks on either side of the ridges are moving away from each other”

Continental drift and plate tectonics go together. Plate tectonics explains how Pangaea became all the continents we

know today.

Continental Drift and Plate Tectonics

There are four main points to plate tectonics :

Here is a short video from YouTube illustrating the

movement of the tectonic plates and the

formation of all the continents over millions

of years ,
