The diagram below shows how hot rock rising up from the Earth's mantle forces its way to the surface to form new sections of oceanic crust at a
mid-ocean ridge. The new crust pushes the older crust away from the
mid-ocean ridge, causing the seafloor to spread. Seafloor spreading
provides evidence for which of the following?
mid-ocean ridge
Lithosphere
Magma
O the law of superposition
the theory of plate tectonics
the theory of natural selection
the law of universal gravitation
