Canada Has a Hole in Its Gravity — And Scientists Know Why

#HiddenNorth #Canada Canada's Hudson Bay sits at the center of one of North America's strangest gravitational anomalies, a region where gravity is slightly weaker than expected. This geography documentary explores the so-called gravity hole over northern Canada and the extraordinary geological forces responsible for this measurable phenomenon. We examine the Hudson Bay gravity anomaly, the immense Laurentide Ice Sheet, and how the weight of ancient glaciers pushed down Earth's crust during the last Ice Age. Using findings from satellite gravity measurements, we explore why the land is still rebounding thousands of years after the ice disappeared, how Earth's mantle contributes to the anomaly, and why scientists continue studying the relationship between glacial history and Canada's changing landscape.
