Bay

[citation needed] The land surrounding a bay often reduces the strength of winds and blocks waves.

In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".

[5] Bays were significant in the history of human settlement because they provided easy access to marine resources like fisheries.

[6] Later they were important in the development of sea trade as the safe anchorage they provide encouraged their selection as ports.

[7] The United Nations Convention on the Law of the Sea defines a bay as a well-marked indentation in the coastline, whose penetration is in such proportion to the width of its mouth as to contain land-locked waters and constitute more than a mere curvature of the coast.
