Why do mountain ranges have stronger gravity then valleys?
I'm pretty sure they don't...
Since force is proportional to mass but inversely proportional to the square of distance, even if the intervening space when being lifted up is completely filled and as dense as the rest of the Earth (neither of which is the case with mountains) the gravitational force would still be lower than at a lower altitude because the distance term in the gravitational equation will overwhelm the mass term.
Correct, I got trolled by this question one time
It would be simultaneously fantastic and terrible if this question was actually worded like this on an actual test. Different parts of me hope that it both was and wasn't.

It wasn't worded exactly like that, actually I went back to the test and know I'm confused. It was the last one from Kraemer invitationals if anyone has that test

But in terms of tectonics, what relevance does this question have?

I think gravity anomalies can help find which part of tectonics were once connected.
It was letter l in the rules

Answer!
Passive margins are not near a plate boundary while active ones are. Passive margins have very little geological activity while active ones have lots.

Question
What are the differences between grabens, horsts, and half grabens?
Answer
Graben - downdropped area bordered by two normal faults. Horst - the higher elevation region between two grabens. Half graben - basically a graben but only bordered on one side by a normal fault
