Coastline features are geographical features that are found along the coast of a body of water. FJORD, RIA, INLET, INLETS, SHORE, and FIORD are all examples of coastline features. A FJORD is a long, narrow INLET with steep sides or cliffs, created by a glacier. A RIA is a coastal INLET formed by the partial submergence of an unglaciated river valley. An INLET is a narrow body of water between two land masses, usually leading to an ocean or sea. INLETS are often referred to as coves. INLETS can also refer to a small bay or arm of the sea. INLETS can also be referred to as bights. INLETS can also be referred to as fiords. A SHORE is the area of land that borders a body of water, such as an ocean, lake, or river. A FIORD is a long, narrow INLET with steep sides or cliffs, created by a glacier.
