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

question 27

Multiple Choice

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

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