The shape, outline, or boundary of a coast.
- The coastline is only 32 m.
- The familiar path down the coastline passed the Cliffs of Moher and continued for a short distance.
- Between the volcanic tract of the Campagna and the sea there is a broad strip of sandy plain, evidently formed merely by the accumulation of sand from the sea, and constituting a barren tract, still covered almost entirely with wood as it was in ancient times, except for the almost uninterrupted line of villas along the ancient coastline, which is now marked by a line of sandhills, some 2 m.
- The coastline is only 25 m.
- The long stretch of sandy foreshore is broken on the coastline by the magnificent cliffs of Malan, the hammer-shaped headlands of Ormarah and Gwadar, and the precipitous cliffs of Jebel Zarain, near Pasni.
