A peninsula is a piece of land that is almost entirely surrounded by water but is connected to the mainland on one side. It is often characterized by water on three sides and land on one side. Peninsulas can vary in size, ranging from small, narrow formations to large land masses. They are formed through various geological processes, including erosion, tectonic movements, and sea level changes.
By studying peninsulas, you will gain a deeper understanding of the Earth's diverse geography and the interconnected relationship between land and water.
