The earths plates moved over millions of years, bringing contenents and others freatures of the earth to their present arrangement. this movement of the lithospehers is explained by . a. continental drift b. the principal of superposition c. the theory of plate tectonics d. nuclear fission

The appropriate answer is c. the theory of plate tectonics. The theory of plate tectonics states that the earth's crust is divided into plates that float on the semi- molten mantle below. the movement is caused by convection currents in the mantle that drags the plates along as they rise and fall in the mantle.
