The 79th Parallel North is a circle of latitude located 79 degrees north of the Earth's equatorial plane. It runs through the Arctic region, primarily over the Arctic Ocean and parts of the surrounding landmasses. This parallel is significant for geographical and climatic studies, as it marks the boundary where the polar climate becomes more pronounced. At this latitude, temperatures are extremely low, and the area experiences long periods of darkness in winter and continuous daylight in summer. The 79th Parallel North is near the northern limits of human habitation and is close to regions like Greenland and the Svalbard archipelago.
