Describe each of these estuaries:
Coastal Plain:
Tectonic:
Bar-built:
Fjord:

Coastal Plain: A coastal plain is a flat, low-lying piece of land next to the ocean. Coastal plains are separated from the rest of the interior by nearby landforms, such as mountains

Tectonic: relating to the structure of the earth's crust and the large-scale processes which take place within it.

Bar-Built: Bar-built or restricted-mouth, estuaries occur when sandbars or barrier islands are built up by ocean waves and currents along coastal areas fed by one or more rivers or streams

Fjord: a long, narrow, deep inlet of the sea between high cliffs, as in Norway and Iceland, typically formed by submergence of a glaciated valley.
