Gakkel Ridge in the context of "Eurasian Plate"

The Danish Realm, officially the Kingdom of Denmark, or simply Denmark, is a sovereign state consisting of a collection of constituent territories united by the Constitutional Act, which applies to the entire territory. It consists of metropolitan Denmark (sometimes called "Denmark proper")—the kingdom's territory in continental Europe and its proximate islands—and the realm's two autonomous (but not sovereign) regions: the Faroe Islands in the North Atlantic and Greenland in North America. The relationship between the three parts of the kingdom is known as rigsfællesskabet (the unity of the realm, which has also been translated into the Danish Commonwealth or the United Kingdom of Denmark).

The Kingdom of Denmark is not a federation, but a concept encompassing the three autonomous legal systems of Denmark, the Faroe Islands and Greenland, united under its monarch. The Kingdom of Denmark is a unitary sovereign state. It has Arctic territorial claims in the Arctic Ocean: various sites near the North Pole (Lomonosov Ridge, Gakkel Ridge, and the Alpha-Mendeleev Ridge complex). The Kingdom of Denmark constitutionally encompasses the realm or the country, but the Faroe Islands and Greenland have an extended degree of autonomy to govern their relations.

The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian plate and the African plate, north and south of the Azores triple junction. In the South Atlantic, it separates the African and South American plates. The ridge extends from a junction with the Gakkel Ridge (Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet triple junction in the South Atlantic. Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level, for example in Iceland. The ridge has an average spreading rate of about 2.5 centimetres (1 in) per year.

The Eurasian plate is a tectonic plate that includes most of Eurasia (a landmass consisting of the traditional continents of Asia and Europe), with the notable exceptions of the Arabian Peninsula, the Indian subcontinent, and the area east of the Chersky Range in eastern Siberia. It also includes oceanic crust extending westward to the Mid-Atlantic Ridge and northward to the Gakkel Ridge.

The Eurasian Basin, or Eurasia Basin, is one of the two major basins into which the Arctic Basin of the Arctic Ocean is split by the Lomonosov Ridge (other being the Amerasia Basin). The Eurasia Basin may be seen as an extension of the North Atlantic Basin through Fram Strait. It is further split by the mid-ocean Gakkel Ridge into the Nansen Basin and the Amundsen Basin. The latter basin is the deepest one of the Arctic Ocean and the geographic North Pole is located there.

The Eurasian Basin is bounded by Greenland, the Lomonosov Ridge, and the shelves of the Laptev Sea, Kara Sea and Barents Sea. The maximum depth within the Eurasian Basin is reached at the Litke Deep with 5449 m depth.

The Laptev Sea Rift is a divergent tectonic plate boundary between the North American Plate and the Eurasian Plate located on the Arctic Ocean coast of northeastern Siberia in Russia. The Laptev Sea Rift is the continuation of the Gakkel Ridge (Mid-Arctic Ridge) into the continental crust of Siberia. It starts offshore in the continental shelf and continues onshore to a point located in the Chersky Range where the boundary motion changes from extension to compression.
