Why is that Hudson Bay area of Canada has 4% less gravity than the rest of the world?
Can you tell me why the Hudson Bay area of Canada has 4% less gravity than the rest of the world?
Yes, the reason for this is due to the last ice age. The large amount of ice caused the Earth's crust to sag downward. As a result, the gravitational pull in that area is slightly weaker than the rest of the world.
