My answer will be the plate tectonic theory that explains a variety of geological features and events and that has to do with, among others, the expansion of the ocean floor.
Answer:
Plate tectonic theory
Explanation: The basic principle of plate tectonic is that lithosphere exists as a separate entity, and different tectonic plates rides on the fluid like asthenosphere. It describes the large scale motion of the seven bigger plates and of several smaller plates of earth's lithosphere. It is based on the concept of continental drift.
