A headland is surrounded on three sides by water. We saw an arch and several places where beaches were formed. A number of stages are involved: All rocks have lines of weakness; the sea and its waves use hydraulic action, abrasion and solution to erode along any lines of weakness. Bays are bodies of water partially surrounded by land, and they are typically less enclosed and smaller than a gulf. Advertisement Advertisement It is formed when the water rises along a slight but important slope due to some net shoreward transport of water when the waves move towards the beach. Toronto Memory Program, a Headlands Research site, is Canada's largest and most experienced site for drug treatment trials in Alzheimer's disease and related conditions. Coastlines where the geology alternates between strata (or bands) of hard rock and soft rock are called discordant coastlines. The bands of soft rock, such as sand and clay, erode more quickly than those of more resistant rock, such as chalk. Cabo da Roca, with cliffs rising 330 feet above the ocean, is the headland forming the westernmost part of Portugal and the European continent.

The red chert photo is from classic exposures in the Marin Headlands along Conzelman Drive, north end of the Golden Gate Bridge. Continued wave action causes the widened crack or cave to break through the headland and form an arch. How did the original headland become eroded to the present coastal landscape? Fjords are made when glacial valleys are filled with water when sea level rises. If a coastline is all made of hard rock, then it will stay relatively firm and resistant to erosion and weathering, and therefore create a headland. They also can be made by people mining off the coast.
