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 ,
