Peninsula

A peninsula is a landform surrounded by water on most sides and connected to a larger landmass by a narrower area of land.

Coastline: The boundary where land meets a sea, lake, or other body of water. A peninsula’s outline is defined by its coastline.
Arabian Peninsula: A large peninsula in southwest Asia bordered by the Red Sea, Arabian Sea, and Persian Gulf. It is the world’s largest peninsula by area.
Plate tectonics: The theory that Earth's outer shell is divided into moving plates. Plate motion can uplift or deform land that forms a peninsula.
Maritime trade: The exchange of goods by sea between ports and regions. Peninsulas can place ports beside major sea routes.
Cape: A prominent point of land extending into a sea or other body of water. A cape is usually a smaller coastal projection than a peninsula.
Isthmus: A narrow strip of land connecting two larger land areas, with water on both sides. A narrow land connection can make a peninsula’s attachment resemble an isthmus.
Iberian Peninsula: A peninsula in southwest Europe occupied mainly by Spain and Portugal. Its distinct European setting makes it a classic regional example.
Sea-level rise: An increase in the average level of the world's oceans. Rising seas can flood low ground and narrow a peninsula’s land connection.
Naval warfare: Armed conflict conducted by naval forces at sea and along coasts. Peninsulas can offer strategic positions while exposing long coastlines.
Promontory: A high point of land that projects into a lowland or body of water. A promontory emphasizes elevated terrain rather than a broad land connection.
