The Gulf has an unusually weak gravity in Canada

The cause of the area around Hudson Bay, Canada has smaller gravity than other places may be due to a large iceberg or convection deep in the ground.

Scientists have just hypothesized the reason why the area around Hudson Bay , Canada has much smaller gravity than other places, said Express on December 14.

One study suggested that the Laurentide ice sheet, which covers much of today's area of ​​Canada and the northern part of the United States, is very massive, forming dents on Earth 10,000 years ago, causing gravity to be " Bend".

The Earth is recovering its original shape at a very slow speed. Scientists believe it will take another 5,000 years to recover normal gravity. Therefore, the area will always have less gravity than other places until the deep dent on the Earth is leveled.

Another hypothesis is that the appearance of convection flow of lava deep in the ground. The Earth's crust is a bubbly flow of lava constantly swirling deep below the planet's surface about 160km. It creates convection currents, which pulls continental tectonic plates down. This process reduces the volume of the area and reduces gravity.

The reduction in gravity means that the weight of the people coming here will be smaller than in other areas. Therefore, many visitors came to Hudson Bay and considered it a natural weight loss place.
