Important Oceanography Information
Seafloor Features:
A: Continental Shelf
B: Abyssal Plain
C: Abyssal Hills
D: Mid Ocean Ridge
E: Continental Slope
F: Trench
Seawater is typically denser than freshwater due to seawater’s higher salinity.
The surface temperature of the oceans is more variable than the water near the ocean floor because most
energy is exchanged at the surface.
Tides will be highest during a new and full phase moon.
Material is added to a continental shelf from deposition of continental sediments.
Sodium and chloride are the two most common ions found in ocean water.
Trenches have the greatest amount of water pressure exerted on them.
If polar ice caps melt the following will happen; increased coastal flooding, increased sea level, and decreased
ocean salinity.
The following features are indications of tectonic activity; mid-ocean ridges, trenches, and seamounts.
Upwelling in oceans brings nutrients to the surface which increases fish populations.
Boats float higher in the Atlantic Ocean than in a River because the ocean has a greater density due to a higher
The Mediterranean has a greater salinity than the Atlantic, Pacific, and Arctic Oceans.
Salt water has a lower freezing point than fresh water.
The surface of the sea is not level because of the following; tides, winds, and currents.
Gases dissolve better in colder temperatures and under greater pressure (deeper in the ocean).
