Rock
First things first. You know beaches, headlands, and spits. Well, maybe not spits. Anyways, spits are long finger like beaches that reach out into the ocean. Okay, back to the point of the question. Beaches, headlands, and spits were all made by WAVES which are caused by wind. Waves are a type of erosion. What makes them, will destroy them. Basically, waves made beaches, headlands, and spits, but, waves will then again destroy them.
Headlands are typically formed by erosion, as the action of waves, currents, and weathering wears away the coastlines, creating protruding landforms. Erosion removes softer rock and sediment, leaving harder rock to form headlands that jut out into the water.
Headlands are inanimate objects they can not act at all.
The member of parliament for Headlands is Mutasa Didymus Noel Edwin.
Mendocino Headlands State Park was created in 1974.
Caspar Headlands State Beach was created in 1972.
Headlands Beach State Park was created in 1953.
Harmony Headlands State Park was created in 2003.
headlands will experience the most, because they are the line of least resistance (sticking out into the sea) and will catch the full force of the waves, as opposed to the bays and shorelines they shelter.
Beach sand eroded from headlands composed of diorite is likely to contain the minerals quartz and feldspar. Diorite primarily consists of plagioclase feldspar and hornblende, and as it weathers, these minerals break down and contribute to the sand composition. Quartz, being highly resistant to weathering, is also commonly found in beach sand due to its prevalence in various rock types.
Basically, a bay is formed first, which is when the coast erodes and makes kind of a C shape. the bits that are sticking out in the sea are called the headlands. headlands erode too, but slowly, because they are made of a hard rock. bays are made of softer rocks, therefore they erode quickly.
As Ireland is an island, there are many headlands around the coast of Ireland, too many to mention.
