One Region in Canada Has Lower Gravity Than Other Parts of the World

In Canada, the Hudson Bay region seems to be “missing” gravity. This strange phenomenon was first identified in the 1960s, according to Global News.

Scientists believe that it’s caused by “a combination of convection occurring in the Earth’s mantle and the Laurentide Ice Sheet, which left an indent on the area after it melted 10,000 years ago.” That indent means less mass, which in turn means less gravity.
