Oceanography Chapter 3 Exam | Test #2
continental shelf
a generally flat zone extending from the shore to the shelf break
The origin of Japan:
a part os an island arc chain that resulted from the convergence of two oceanic plates
Hydrothermal vents are located near:
active areas of seafloor spreading.
Ocean Trench
deep linear scars on the deep-ocean floor caused by plate convergence
Passive continental margins are characterized by all of the following except:
deep-sea trenches.
abyssal plain
flat depositional surfaces that cover extensive portions of the deep-ocean basins
The origin of Hawaii
formed over a hot spot
Transform faults have all of the following characteristics except:
movement occurs in the same direction.
Submarine canyon
narrow and deep valleys on continental slopes
New lithosphere is produced in association with ________.
oceanic ridges
Along the margins of the Pacific are found most of Earth's:
oceanic trenches.
Active continental margins are located:
on the west coasts of both North and South America.
With respect to mid-ocean ridges, transform faults are:
perpendicular to the ridge axis.
continental margin
shallow-water areas close to continent
The correct order of seafloor features from the coast to the mid-ocean ridge is:
shelf, slope, rise, abyssal plain.
The method that used most frequently to investigate sediment and rock layers of the sea floor is:
sound waves (specifically seismic reflecting profiling).
Relatively few abyssal plains are located in the Pacific Ocean due to:
the presence of convergent active margins.
satellites are used to map the ocean floor because:
the shape of the ocean surface reflects large features on the seafloor
Directly seaward of the continental shelf is a more steeply sloping region called the ________.
continental slope
Oceanic ridges and rises result from seafloor spreading along:
divergent plate boundaries.
Submarine canyons were most likely formed by:
erosion by turbidity currents.
Which of the following features is related to transform faults along mid-ocean ridges?
Fracture zone
Ninety East Ridge
Indian Ocean
Walvis Ridge
Indian Ocean
Origin of Ascension island
Island is/ are an outcrop of the mid-ocean ridge (a divergent boundary)
How were the British Isle (Great Britian) formed
Island/s is/are part of a continent but is separated by a shallow body of water
(**going to be on test)Grand Banks
North Atlantic
Eltanin Fracture Zone
North Pacific
Characteristics of active continental margins include all of the following except:
broad continental shelves.
South Sandwich Trench
South Atlantic
