A cape is a geographical feature that typically extends into a body of water, such as an ocean or sea. It is formed by the erosion of the coastline, resulting in a point of land projecting outwards into the water.
A thin strip of land that extends into a body of water is called a "peninsula." It is surrounded by water on three sides and is connected to the mainland by a narrow strip of land. Peninsulas can vary in size and shape.
If it is small and doesn't stick out a lot it is called a cape. If it sticks out more, it is called a peninsula.
