WebNarrow, deep, steep-walled inlet formed by the submergence of a mountainous coast or by the entrance of the ocean into a deeply excavated glacial trough after the melting of the glacier; a deep, small-surface-area estuary with moderately high river input and little tidal mixing. Protruding bits of land called headlands absorb much wave energy. [6] Later they were important in the development of sea trade as the safe anchorage they provide encouraged their selection as ports.

The erosion-resistant Blue Ridge is the highest part of the Appalachian Mountain range. Massive glaciers retreated, leaving a carved-out landscape behind. For example, the North Sea borders the Atlantic Ocean. The complex tectonic activity in the area has created earthquakes for thousands of years.

Rivers transport sediments and deposit them at the mouths of tributaries and along margins of the Bay, forming broad, flat deposits of mud and silt. Along the southern side of the Bay, a very subtle topographic rise separates the rivers flowing north to the Chesapeake Bay in Virginia from those flowing south to North Carolina.

Sea level at that time stood approximately 30 feet (9 m) lower than the present level. The spit is then called a bay barrier or a bay-mouth bar. Oceans and bays are large water bodies. Millions of years later, the prehistoric Susquehanna River carved a 400-foot deep canyon as it flowed from the Appalachian Mountains toward the Atlantic Ocean. An estuary is an area where a freshwater river or stream meets the ocean. Debris in the estuary, including fuel, garbage, sewage, and ballast, remained unregulated for decades.Runoff from agriculture and industry in New York and New Jersey also contributed a toxic estuarine environment. Calculate the expected change in nitrogen and oxygen. The Chesapeake Bay watershed includes six different geologic areas, called physiographic provinces: Continental Shelf, Coastal Plain, Piedmont, Blue Ridge, Valley and Ridge, and Appalachian Plateaus.

Barrier Island: an island or group of island, usually in the ocean, that protects the nearby mainland coast from erosion. The modern Chesapeake Bay watershed is framed by mountains on the north and west and the lower elevations on the east and south that formed from the slow collision of the African and North American tectonic plates. The sea erodes the softer rock faster than the harder rock, forming a bay.
