By which mechanism does older oceanic rocks move at a ridge? 1. magnetic forces move the rock 2. continents drift and move the rock 3. the ridge subducts and moves the rock 4. new molten material rises and moves the rock

The answer is; 3

The ridge is a subduction zone. The oceanic plate usually subducts below the continental plate. Old crust is consumed at convergent boundaries while new crust is formed at divergent boundaries by uprising magma from the mantle. This movement of plates is powered by convection currents of the mantle.
