A north south oriented shoreline has land to the east and the major storm waves arrive from the southwest. A headland abuts westward along the shoreline and exposes a distinctive black basalt that is rapidly eroded by waves pounding the coast. Where would you expect to find black sand derived from this headland?
◦ on the beach to the north of the headland
◦ on the beach to the south of the headland
◦ only in pocket beaches along the headland
◦ immediately offshore of the headland
