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
