Some parts of Canada and especially The Hudson Bay, have less gravity than the rest of the earth.
This paradox was first identified in the 1960s when the Earth’s gravity fields were being mapped. Since then, scientists have been trying to figure out what is causing this anomaly but, up until today, they don’t know the exact answer.
During all these years, several theories have been developed but none is unanimously accepted by the scientific community. The most common belief is that it could have something to do with convection occurring in the earth’s mantle. The mantle is a layer of molten rock (magma) which is located below the surface of the Earth. It’s extremely hot and constantly moving chaotically creating convection currents. These convection drags the Earth’s continental plates down, which decreases the mass in that specific area and decreases the gravity (gravity is proportional to mass).

But this is just a theory; it has not been scientifically proven yet. For the time being no-one knows exactly why this is happening but scientists are still working on it.
