A
This type of ocean sediment is commonly found from precipitation of minerals at hydrothermal vents
hydrogenous
a complex of living organisms interacting together with their abiotic environment
Ecosystem
This deepest of ocean features is created at subduction zones
Trench
This process causes fluids moving in the Southern Hemisphere to be deflected to their left
Coriolis Force
The average salinity of seawater
35‰
This is an area of rapid change in salinity with a change in depth
halocline
These are large, circular sea surface flow patterns caused by global air currents
gyres
Dissolved salts in seawater ultimately comes from a chemical reaction between these three things
water, CO2 and rocks on land
This type of marine sediment is made primarily of hard parts of marine organisms
Biogenous
This ocean feature rises high above the sea floor but does not break the sea surface
seamount
The part of the water column that has more than 0% but less than 1% of surface sunlight
Disphotic zone
Besides NaCl, these are the two most abundant dissolved ions in seawater
magnesium and sulfate
Higher than average sea surface salinity is typically found at this latitude
~30° N/S
These air currents combine with the Coriolis Force to produce the Trade Winds and Westerlies
Hadley cells
Ocean crust will typically be thinner the farther away it is from this ocean feature
divergence zone/mid-ocean ridge
Old oceanic crust is destroyed in these ocean regions
subduction zones/trenches/convergent plate boundaries
Subduction zones are found at this type of plate boundary
Convergent
This ocean region is composed of the continental shelf and continental slope
Continental margin
The ocean province that lies offshore of the Neritic province
Oceanic province
A name for biogenous sediment that is >30% calcite or silica
ooze
A flat-topped seamount that was once a volcanic island but subsided beneath the sea surface
Guyot
These small hills (<300m) rise from the floor of the abyssal plain
Abyssal hills
This ocean feature is formed by a large river valley being submerged by sea level rise
submarine canyon
This type of continental margin is found along the coast of Florida
passive
Formation of coastal mountain ranges and volcanic island chains are typically found along this type of continental margin
active
