What best describes a peninsula?

A peninsula is best described as a land projection extending into the water. This geographical feature is characterized by being surrounded on most sides by water while remaining connected to the mainland on one side. This connection to the mainland distinguishes a peninsula from other landforms like islands, which are entirely surrounded by water.

The definition emphasizes the unique positioning of a peninsula, showcasing its role as a prominent feature in coastal geography. It serves as a critical piece of land that can influence local climates, ecosystems, and human settlement patterns along the coast. Understanding this concept is important when studying geography, as it highlights how landforms can interact with bodies of water.
