Question

The seafloor spreads in opposite directions as magma forces its way upward. Geologists have observed matching, reversed magnetic bands

on both sides of this ridge. Which is the best explanation of these matching, reversed bands?
A. Magma is so hot that it mixes the magnetic direction.
B. The pushing of lava and rock creates enough pressure to affect magnetic direction.
c. The position of the Earth in relation to other planets causes magnetic changes.
D. The Earth experiences cycles of magnetic poles reversing.
E. The earthquakes resulting from the magma movement cause the magnetic changes.

D. The Earth experiences cycles of magnetic poles reversing. This phenomenon is known as geomagnetic reversal, where the Earth's magnetic field periodically flips its orientation, causing the magnetic bands to appear in reverse order on both sides of the spreading seafloor.
