top | item 34133808 (no title) spiffistan | 3 years ago Considering continental drift is about 2.5cm per year (or one inch)...about 50km from where it is today. discuss order hn newest gepardi|3 years ago Is there consensus that continental drift has been constant? What if it was much faster at the beginning and has slowed with time?In that case it would be hard to know its location 2 million years ago. legostormtroopr|3 years ago If continental drift were off by a factor of 10, it would be 500km from where it is now.And given that Greenland is about ~2500km long North-South, even if it drifted Northward the whole time, it’d still be mostly in the Arctic circle.
