What is a peninsula?
A peninsula (Latin from paene "almost" and insula "island") is a piece of land that is bordered by water on three sides but connected to the mainland. The surrounding water is usually understood to belong to a single contiguous body, but is not always explicitly defined as such. A peninsula can also be a headland, cape, island promontory, bill, point, or spit. A point is generally considered a tapering piece of land projecting into a body of water that is less prominent than a cape.
Due to their unique geographical location, peninsulas are usually places of amazing beauty and diverse flora and fauna.
The largest peninsula on the planet is Arabian peninsula. A lot of countries are located there: parts of Jordan and Iraq, Saudi Arabia, Qatar, Yemen, Oman.
