In this article, I wanna walk you through Important Peninsulas in the World – for UPSC IAS.

Peninsula – (paene “almost” and insula “island”) A peninsula is a landform surrounded by water on most of its border (three sides) while being connected to a mainland from which it extends. The surrounding water is usually understood to be continuous, though not necessarily named as a single body of water.

Peninsulas are not always named as such; one can also be referred to as a headland, cape, island promontory, bill, point, fork, or spit.

A river which courses through a very tight meander is also sometimes said to form a “peninsula” within the (almost closed) loop of water.

Varying in sizes, they could range from the Arabian Peninsula, one of the largest peninsulas in the world to much smaller ones.
