What “coastline” means

Wiktionary · Wikipedia

coastline

  • nounThe shape, outline, or boundary of a coast.
Full entry on Wiktionary →

A coast is the land next to the sea or the line that forms the boundary between the land and the ocean or a lake. Coasts are influenced by the topography of the surrounding landscape and by aquatic erosion, such as that caused by waves. The geological composition of rock and soil dictates the type of shore that is created. Earth has about 620,000.0 km (385,250.1 mi) of coastline.
