Arctic
Fjord estuary (glacier regions)
Are characterized by a deep elongated basin that is U-shaped and a ledge or barrier that separates the basin from the sea.
Tectonic estuary (San Diego)
Are created when the sea fills in the "hole" or basin that was formed by sinking land.
Bar-built estuary (Destin)
Are formed when sandbars build along the coastline.
What is an estuary?
Area where the river meets the ocean/brackish water.

How did hurricane Katrina cause such destruction to New Orleans?
Hit the coast with force, transportation and communication was cut off.
Forests can help in controlling?
Hurricane damage and global warming
How would a drought affect the salinity of estuary water?
Increase salt levels due to less runoff.
What ocean was the first to be explored?
Indian
What organization did Bob Ballard talk about?

How does the salinity of the water in an estuary change during tidal flooding?
Salinity will increase
How are deltas formed?
Sediments from erosion.

tides
