Question

which two theories were combined in the theory of plate tectonics?
o the theory of continental drift and the theory of seafloor spreading
o the theory of everything and the theory of continental drift
o murphys law and the theory of continental drift
o seafloor spreading and murphys law

Explanation:

The theory of plate tectonics combines the theory of continental drift (which proposed that continents move across the Earth's surface) and the theory of seafloor spreading (which describes the creation of new oceanic crust at mid - ocean ridges). The other options involve non - relevant theories like the theory of everything (a theoretical physics concept), and Murphy's law (a humorous adage).

Answer:

the theory of continental drift and the theory of seafloor spreading
