Question

new crust is found at the center of the ____, proving the movement of the seafloor and th
mountains
ocean
earth
continents

Explanation:

Seafloor spreading occurs at mid - ocean ridges. New crust is formed at the center of the ocean (mid - ocean ridges) as magma rises and solidifies. This process is evidence of seafloor movement. Mountains are formed by tectonic processes like collision of plates (not directly related to new crust formation for seafloor movement evidence). The center of the earth is the core (not where new crust for seafloor movement is found). Continents are made of continental crust which is different from the oceanic crust formed at mid - ocean ridges.

Answer:

ocean
