Question 1

How can you tell from the apparent polar wandering curves for Eurasia and North America, when they were last together and had just started to drift apart?

Accepted Answer

A)  more than 500 million years ago, because the curves are separated then 
B)  just recently, when the curves came together 
C)  about 300 million years ago, because the curves really bend before that 
D)  about 200 million years ago because, for times older than that, their curves remain parallel and about the same distance apart
