Final answer:
The idea that California will sink into the ocean is not consistent with the theory of plate tectonics.
Step-by-step explanation:
The idea that California will sink into the ocean is not consistent with the theory of plate tectonics. According to the theory, California is located along the boundary between the Pacific plate and the North American plate.
These plates are moving past each other horizontally, which can result in earthquakes along the San Andreas Fault. However, plate tectonics does not suggest that landmasses like California will sink into the ocean.
