When the ice finally started melting, the earth bounced back (or at least it tried to). Based on analysis of gravity and magnetic data and published field evidence, we propose a new tectonic model in which Proterozoic crust in the southeastern third of Hudson Bay formed within an oceanic or marginal-basin setting proximal to the Superior craton, whereas the northwestern third is … 5 years ago. Giants Causeway, County Antrim, Northern Ireland, Sixty million years ago a huge volcanic eruption spewed out a mass of molten basalt, which then solidified and contracted as it cooled, creating the cracks that can be seen today. Let’s figure out just how. And voila! A new theory to account for the Hudson Bay area’s missing gravity concerns the Laurentide Ice Sheet, which covered much of present-day Canada and the northern United States. During the ice age, the entire country of Canada was covered by a huge glacier known as the Laurentide Ice Sheet. Since the mass of rock decreased, so did gravity. Based off science stuff, this should Hudson Bay has less gravity as compared to the rest of the world. It’s a result of mass, which means the varying density of the Earth at different locations can affect how much you weigh there. Geology. Express. Home; Apartment; Beaches; Leisure & Visits.

That’s how we got such an irregularity. It has been revealed that the Laurentide Ice Sheet, which covered much of present-day Canada and the northern United States, was so large that it dented the earth 10,000 years ago, literally bending gravity. The colours range from purple (low gravity), through blue, green (normal) and yellow to red (high). Source(s): https://shrink.im/baqeS. If you have studied physics then you will know that gravity is a result of mass. But there is also another reason why the Hudson Bay defies the laws of physics – it is a convection current hot spot. Current models of the Laurentide deglaciation predict only 15% to 30% of the observed Hudson Bay Free‐air gravity anomaly low. Anonymous. Hudson has long fascinated believers in the supernatural, with many scientists assuming its distinctive shape was formed from tectonic activity, but a growing school of experts believes it could have come to be because of extraterrestrial activity.
