Answer to Question 1

Sunspots always come in pairs, with one being a north pole and the other a south pole. One sunspot leads the pair. All of the leading spots in the northern hemisphere will have the same polarity, and all the ones in the southern hemisphere will have the opposite polarity. For example, if the leading sunspot in the northern hemisphere is a north pole, then all the leading spots north of the equator will be a north pole, and all the leading sunspots in the southern hemisphere will be a south pole.

Answer to Question 2

South America and Africa were split by the mid-Atlantic rift, and have spread apart in the last 70 million years.
