Term
Estuary
Definition
A semi-enclosed area at the mouth of a river where fresh water and seawater mix
Term
Euryhaline
Definition
Species that can tolerate a wide range of salinities
Term
Stenohaline
Definition
Species that can tolerate a narrow range of salinities
Term
Brackish
Definition
Water that is less salty than salty that seawater but saltier than fresh water
Term
Wetlands
Definition
Estuarine areas of high elevations that are periodically covered with water
Term
Mudflats
Definition
Wide expanses of an estuary that are exposed during low tide
Term
Meiofauna
Definition
Microscopic organisms living in between marine sediment particles
Term
Channels
Definition
Estuarine areas where water is present both during high and low tides
Term
Black Mangroves
Definition
are always in a tropical climate.
Term
Pneumatophores
Definition
Pencil thin root extensions on black mangroves
Term
Red Mangroves
Definition
"island makers"
Term
Cord Grasses
Definition
grow in the lowest part of a salt marsh
Term
Suspended Sediments
Definition
clog organs of filter feeders in mudflats
Term
Channels
Definition
Where juvenile fishes are found
Term
Outwelling
Definition
the excess flow of detritus to nearby ecosystems
Term
Glaciers melting
Definition
the reason ocean levels of the world rose to form most estuaries
Term
type of prey
Definition
what is determined by bill length
Term
Salt wedge
Definition
what is formed when sea water moves across bottom of estuary and freshwater across top
Term
Left side
Definition
The side with the most salinity in the Southern hemisphere
Term
Pneumatophores
Definition
extract oxygen for black mangroves
Term
Fluctuating Salinity
Definition
caused by levels of missing water (True)
Term
An abundance of plants and macroscopic life
Definition
what are present in mudflats (False)
Term
Large boulders in Montana
Definition
Are not evidence of glaciers (False)
Term
Many ice ages
Definition
Uniformitarian view (True)
Term
Fjord
Definition
most common type of estuary (False)
Term
Estuary is a productive ecosystem because...
Definition
many fish and shellfish found there, plenty of nutrients for primary producers, lots of nitrogen-fixing bacteria, enough detritus, and estuaries participate in outwelling, in which their excess resources flow into the ocean
Term
One ice age
Definition
Catastrophic view (True)
