In Canada’s Hudson Bay region, gravity is slightly weaker than in most places on Earth due to a natural “gravity anomaly.” Scientists explain this by two main factors: the lingering effects of the last Ice Age, when massive glaciers compressed the land and left less dense material beneath the surface, and the slow movement of molten rock deep within the Earth’s mantle. Together, these processes create a measurable, though subtle, reduction in gravity in the area.
