Salient in geography is a fancy word that describes a piece of land that sticks out like a nose on a face. Imagine taking a step back and looking at a map. If you notice a little piece of land that sticks out into water or is surrounded by water, that's a salient. It can look like a triangular or a crescent shape.
For example, think about the state of Michigan in the United States. It juts out into the Great Lakes and therefore, Michigan is a salient. Another example is the Kalinga region in the Philippines, which is a peninsula that sticks out into the South China Sea.
Salients are important in geography because they have unique features and can be used as natural borders or barriers. They can also affect the weather and climate of the surrounding areas, as well as impact transportation and trade routes.
