Rock topple?
Correct!
A rock topple, or more (more simply) a topple, is the most deadly form of landslide, due to the fact that it is literally part of the rock face peeling off the rock body and toppling over (think onion layers, except these layers are made of huge rock, and the ant quivering right where it's going to land is you).
I'll give someone else a chance to ask a question
To clarify, does that mean it's my turn to ask a question or no?
Yes, it's your turn.

Sorry, forgot about this thread haha.

Name a couple of reasons why the continents do not have a perfect jigsaw fit.

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.
