A peninsula is a piece of land that is almost entirely surrounded by water, but connected to a larger landmass by a narrow strip of land called an isthmus.

Think of it like a finger pointing out into the water!

Here's a breakdown:

* Land: A peninsula is primarily land.

* Almost entirely surrounded by water: It has water on three sides.

* Connected to a larger landmass: It's attached to a mainland, continent, or larger island.

* Isthmus: The narrow strip of land connecting the peninsula to the larger landmass is called the isthmus.

Examples of peninsulas:

* Florida, USA: It's connected to the mainland by a narrow isthmus.

* Italy: It's connected to mainland Europe by the narrow strip of land known as the Po Valley.

* Korea: The Korean peninsula is connected to mainland Asia by the narrow land bridge of Manchuria.

* Arabian Peninsula: It's connected to Asia by the Isthmus of Suez.
