Harry Hess, Who proposed the seafloor spreading hypothesis?, One tectonic plate sinks beneath another., What happens during subduction at an ocean trench?, True, Are oceanic rocks near mid-ocean ridges generally younger than rocks farther away?, False. Sediments are generally thicker farther away because older seafloor has had more time to accumulate sediment., Are sediments generally thicker near mid-ocean ridges because the rocks there are older?, Deep areas of the ocean floor where one tectonic plate sinks beneath another., What are ocean trenches?, It shows that oceanic crust moves and helps drive tectonic plate movement., How does seafloor spreading support the theory of plate tectonics?Deep areas of the ocean floor where one tectonic plate sinks beneath another.
