Earth's magnetic field is not directly related to plate tectonic motion. It is generated by the movement of molten iron in the outer core and has a different origin and mechanism than plate tectonics. The other three features are all closely tied to plate tectonics: the "ring of fire" is caused by the interactions between tectonic plates and results in volcanic activity and earthquakes, deep ocean trenches are associated with subduction zones where one plate is being pushed underneath another, and mountain ranges are often formed by the collision and uplift of two converging plates.
