* Surrounded by water: Both peninsulas and islands are landmasses surrounded by water.
* Connected to a larger landmass: A peninsula is a piece of land that projects out into a body of water but is still connected to a larger landmass. An island is a piece of land completely surrounded by water, meaning it's not connected to any other land.
* Distinct geographical features: Both peninsulas and islands often have unique geological formations, ecosystems, and landscapes due to their isolation from surrounding land.
Here's a simple way to think about it:
* Peninsula: Like a finger sticking out of a hand.
* Island: Like a hand completely separated from the arm.
While they share similarities, the key difference lies in their connection to the mainland. A peninsula is "almost" an island, but connected, while an island is completely detached.
