Does tectonic plate size affect earthquake magnitude?
I believe it does.
If you imagine it with a bowling ball and two tennis balls, when
you roll one tennis ball into another stationary tennis ball, it
rolls away, but not that far. Now repeat the same experiment with a
bowling ball and a tennis ball, the result is much clearer as to
which moved the stationary tennis ball more. The bowling ball did
as it has a larger mass and size.
