I'm sure this is silly and won't be terribly difficult to answer: can one climb atop a mountain or is it proper to say climb on top of. Or does it matter? I'm thinking the latter is correct.

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.If this question can be reworded to fit the rules in the help center, please edit the question.
I don't think you would do either of these to a mountain, you would simply climb a mountain. Otherwise, they're interchangeable but atop is less used. Humpty Dumpty might sit atop a wall, but most other people would sit on top of one.
