The 75th Parallel North is a circle of latitude located 75 degrees north of the Earth's equatorial plane. It runs through the Arctic region, primarily over the Arctic Ocean and parts of the landmasses of Greenland and Canada. This parallel is significant for navigation and climate studies, as it marks a boundary where the polar climate becomes more pronounced. At this latitude, the sun does not set during the summer months, leading to continuous daylight, while in winter, it experiences polar night, where the sun does not rise. The area around the 75th Parallel North is sparsely populated, with few human settlements, primarily due to its harsh environmental conditions.
