How Does the Polar Wander Curve for Eurasia Confirm Wegener's

question 34

Multiple Choice

How does the polar wander curve for Eurasia confirm Wegener's hypothesis that the Carboniferous (300 million years ago) coal beds were originally deposited when that land mass was near the equator?

• A)To restore the 300 million year paleopole to today's north magnetic pole pushes Eurasia about 40 degrees of latitude farther south than it is today.
• B)To have that pole position, the 300 million year coal beds must have had a steep magnetic inclination.
• C)This means that Eurasia used to sit in the middle of the north Pacific Ocean 300 million year ago where the climate is warmer.
• D)300 million years ago, the equator and magnetic poles had switched positions, so Eurasia was tropical then.
