Question

question 9 what phenomenon describes the formation of new oceanic crust, supporting continental drift? plate tectonics subduction zones seafloor spreading magnetic reversal choose a response...

Explanation:

Seafloor spreading is the process where new oceanic crust forms at mid - ocean ridges and moves away from them, which supports the theory of continental drift. Plate tectonics is a broader theory that includes seafloor spreading. Subduction zones are areas where one tectonic plate moves under another. Magnetic reversal is about changes in the Earth's magnetic field direction.

Answer:

Seafloor spreading
