which concept is described in the theory proposed by hess?\ncontinents do not move.\ncool rock pushes through the crust.\ntrenches are sites of seafloor spreading.\nmid - ocean ridges are sites of seafloor spreading.
Answer
Brief Explanations:
Hess proposed the theory of seafloor - spreading. Mid - ocean ridges are the key sites where new oceanic crust is formed during seafloor spreading. Continents do move according to plate tectonics. It is hot, not cool, rock (magma) that rises through the crust. Trenches are sites of subduction, not seafloor spreading.
Answer:
Mid - ocean ridges are sites of seafloor spreading.
