A peninsula is a part of land that extends into the sea orlakeThe other part is connected to the mainland or larger islands, and the other three sides are surrounded by water.In terms of distribution characteristics, most of the world's major peninsulas are located on the continental margin.
EuropeWith its winding coast and numerous peninsulas, it is known as the "continent of peninsulas".There are five peninsulas with an area of more than 100000 square kilometers: Scandinavia in Northern Europe (the fifth largest peninsular in the world), with an area of 750000 square kilometers (800000 square kilometers in one word[1]);The Iberian Peninsula in southwest Europe (mainly including Spain and Portugal) covers an area of 584000 square kilometers;Balkan Peninsula in Southeast Europe, with an area of 500000 square kilometers;The Apenning Peninsula in southern Europe covers an area of 140000 square kilometers;Northeastern EuropeanKola Peninsula(within Russia), covering an area of 100000 square kilometers.The Great Peninsula is mainly formed by tectonic faulting. The main feature of the peninsula is both land and water. If other conditions are good, it will become what people call the dominant circle of the peninsula.Spit Hehai Cape is also a kind of peninsula.

edit
The Great Peninsula is mainly formed by geological tectonic faulting, such as China'sLiaodong Peninsula、Shandong Peninsula 、Leizhou PeninsulaEtc.In addition, as the sediment carried by the coastal sediment flow accumulates from land to island, or the island is eroded by sea waves, the debris material accumulates from island to land, gradually connecting the island to land, formingContinental island, such as Shandong Province, ChinaZhifu Island。In terms of distribution, the major peninsulas in the world are on the edge of the mainland.[2]
