A peninsula[1][2] is a landform that extends from a mainland and is surrounded by water on most sides.
[6][7] The word peninsula derives from Latin paeninsula, from paene 'almost' and insula 'island'.
[3] A peninsula is generally defined as a piece of land surrounded on most sides by water.
[14] This may create bodies of water that surround the land, forming peninsulas.
[26] Sea level rise from global warming will permanently reduce the size of some peninsulas over time.
[28] The landform is advantageous because it gives hunting access to both land and sea animals.
