What depth do continents have the best jigsaw fit at?
1. After separating, deposition or erosion could occur, which changes the shape of the pieces. Isostatic and eustatic change can also make blocks look like they don't fit. 
2. Around 1000 m or 1 km below current sea level.
Yep, your turn.

To be fair, it was independently discovered by both, so both answers are fair game.

Oof, Leibniz and Newton all over again.

It does bother me, though, when answer keys to tests only list the more widely known one - it risks taking off points for the few students who might have added another answer from having done more research.

I guess I'm partially wrong then.

Who wrote “History of Ocean Basins” in 1962?
