põhjapoolusel

Põhjapoolus refers to the northernmost point on Earth, also known as the Geographic North Pole. This point is not a fixed landmass but rather a location in the Arctic Ocean. The Earth's axis of rotation intersects the surface at the geographic North and South Poles. The North Pole is characterized by a constantly shifting ice pack, with sea ice thickness varying seasonally and over longer periods due to climate change.

Unlike the South Pole, which is located on the continent of Antarctica and has a permanent land base, the North Pole is a dynamic environment. There are no countries located directly at the North Pole, though several nations have territorial claims in the Arctic region. The closest landmass is Canada's Ellesmere Island to the northwest and Greenland to the east.

The North Pole experiences six months of daylight during the summer and six months of darkness during the winter. Due to its extreme location and harsh conditions, permanent human settlement is not feasible. Expeditions to the North Pole are challenging undertakings, typically involving icebreakers, specialized aircraft, or adventurous overland traverses. The exploration and scientific study of the Arctic region, including the North Pole, are of increasing importance due to its sensitivity to climate change and its potential resources.
