Based on our science, the universe could have three possible shapes dependant on the amount of matter in it, the matter affects the curvature of the universe, linked to its shape and geometry. For example, a closed Universe will have a positive curvature, meaning that the average density is more than the critical density. An open universe, on the other hand, would have a negative curvature, and therefore the qaverage density would be less than the critical density. A flat universe would have no curvature and the average density would be equal to the critical density. These shapes relate to the fate of the universe, a closed universe would be finite, an open universe would be infinite and a flat universe would be infinite with no curve.

Answer:true
Explanation: Seventy-five percent of Canada's population resides in a narrow 150-kilometre band pushing up against the U.S., with close ties south of the line.
Answer:
The margins of glaciers are usually darker than the interior primarily because: Growth and associated glacial erosion. When glacial accumulation is greater than glacial ablation, the result is glacial. retreat and associated glacial deposition.
