Here's why:

* High point of land: Headlands are typically formed by cliffs or elevated areas along the coast.

* Extending into the ocean: They jut out into the sea, often creating a prominent feature in the coastline.

* Resistant to erosion: Headlands are usually made of harder rock types, like granite, that are more resistant to the erosive forces of waves and tides. This makes them stand out compared to the softer rock that erodes away around them.
