How are oceans formed by plate tectonics
WebThe Theory of Plate Tectonics explains the geologic processes that, together with surface processes, produce Earth’s features. In addition, it provides a context for understanding the history of Earth. For example, plate tectonics explains how now-separate land masses can share features that indicate that the continents were once connected.
