Question

1. Magnetic reversals are created when Earth's magnetic field flips. What causes this flip?

a.The flipping of Earth's magnetic field is tied to the large ocean currents. As continents move around, the ocean currents also shift. This shifting causes changes in the Earth's magnetic field, even to the point of creating reversals.

b. There is no consensus among geologists.

c. The Earth's mantle is a fluid but not completely elastic. It spins with the general spin of the Earth. However, Once the mantle's elastic limit is reached it begins to spin in the opposite direction. This creates the opposite polarity called a magnetic reversal.

d. The Earth's magnetic field has a half-life of about 7 million years. After that time it declines and then re-establishes itself. If the new resurrection is opposite of the initial polarity it is called a reversal.

Explanation / Answer

Answer is b There is no consensus among geologists.

Magnetic reversals are created when Earth's magnetic field flips. What causes this flip for this question each geologist think differently so there is so no consensus among geologists.
