Abyssal plains are more extensive on the floor of the Atlantic as compared those on the
floor of the Pacific
Sediments of the continental rise can exhibit characteristics similar to those formed by
rivers on land.
The deepest portions of the ocean are part of the relatively narrow features called
Due to the very harsh environment, few organisms are found in association with
The two relatively flat areas on the hypsometric curve represent
some interior continental areas/ coastal plains and abyssal plains
The method that is most frequently used to investigate sediment and rock layers of the sea floor is:
Satellites are used to map the ocean floor because they
a. are unaffected by surface weather.
b. can cover areas where ships have not produced surveys.
c. can "see" large areas of the seafloor at one time.
d. the shape of the ocean surface itself reflects large features on the seafloor below
Passive continental margins are characterized by all of the following
a. broad continental shelf.
c. shallow coastal waters.
d. thick sediment accumulation.
e. very little volcanic and earthquake activity.
Characteristics of active continental margins include all of the following
b. chains of islands.
c. deep-sea trenches.
d. thin sediment accumulation.
e. volcanic and earthquake activity.
The correct order of marine provinces from the coast to the mid-ocean ridge is
shelf, slope, rise, abyssal plain.
Directly seaward of the continental shelf is a more steeply sloping region called the:
All of the following are considered part of the continental margin
a. continental rise.
b. continental shelf.
c. continental slope.
e. submarine canyon.
Abyssal hills are only visible in the Pacific Ocean because
they are higher in the Pacific than in the other ocean basins
