Which is the transfrom fault boundary that separates two great sections of Earth's from fault boundary that separates two great sections of Earth's lithosphere: the North American plate and the Pacific plate. Other faults are small and capable of producing only minor earthquakes.
Most of the displacement that occurs along faults can be satisfactorily explained by the plate tectonics theory, which states that large slavs of Earth's lithosphere are in continual slow motion. These mobile plates interact with neighboring plates, straining and deforming the rocks at their margins.
