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

Here's a simple breakdown:

* Peninsula: A landform that sticks out into the water.

* Almost surrounded by water: There's a small connection to the mainland, but the rest of the peninsula is surrounded by water.

* Connected to a larger landmass: This is the key difference between a peninsula and an island. An island is completely surrounded by water.

Examples of peninsulas:

* Florida, USA

* Italy

* Arabian Peninsula

* Iberian Peninsula

* Korean Peninsula
