Question

1. What was the concept of Polar Wandering based upon?

a.Polar wandering is based on the concepts of plate tectonics. By moving the continents to their former positions (about 400 million years ago) it was found that there were actually two north poles (and two south poles) have moved indenpendently over geologic history.

b. It was based on astronomical observations of other planets. Other planets have magnetic poles that are at much greater angles than Earth's current poles. It is believed that these shifts are responsible for magnetic reversals.

c. The apparent shift of magnetized rocks of different continents. These rocks showed that the poles moved away from the current pole positions over millions of years in the past.

d. The shifting of the magnetic poles is based on the fossils found in different areas of the continents. The occurrence of tropical flora and fauna in areas that are now polar regions indicates that the magnetic poles have shifted in time.

Explanation / Answer

C

According to Polar wandering scientist thought that the poles have moved over geological time but later they found that it's not the poles that moved but the tectonic plates
