Which of the following statements is FALSE?
Seafloor spreading happens when magma from deep within the Earth rises through mid-ocean ridges to form new oceanic crusts.
Rocks near the crest of the mid-ocean ridges are older and are progressively younger further away from the mid-ocean ridges.
The formation of new oceanic crusts at mid-ocean ridges explains why oceanic crusts are younger than continental crusts.
The destruction of older oceanic crusts at trenches explains why there is little sediment accumulation at oceanic trenches.
Draw magnetic striping about a mid-ocean ridge to support the plate tectonics theory.
