b. Marginal seas usually have restricted circulation with the adjacent open ocean
c. Local river input might reduce the salinity of the marginal sea
d. All of the above
The abyssal plain
a. Drains large river systems such as the Amazon River
b. Is an average of about 4,000 m deep
c. Actually has a slope of 3 degrees seaward
d. Never connects with an oceanic trench
As one proceeds away from a mid-oceanic ridge

a. One finds that first the ridge is magnetically neutral, but then there is a polar magnetic
field
b. The oceanic crust becomes younger and younger
c. The oceanic crust becomes older and older
d. The ridge has a reversed magnetic field, which reflects its formation many thousands of
years ago
Parts of the oceanic crust where new crust originates are known as
a. Subduction zones
b. Mid-oceanic ridges
c. Transform faults
d. Plates
Plate boundaries include
a. trenches
b. mid-oceanic ridges
c. transform faults
d. all of the above
Which of the following is a reasonable rate of seafloor spreading
a. one meter per year
b. one cm per year
c. one cm per million years
d. ten cm per million years
A study of oceanic geology shows that there are few oceanic crustal rocks found that are older
than 80 million years. Why?
a. Oceanic crust was not formed until the beginning of the Precambrian, 80 my ago.
b. Current radiometric dating techniques cannot date rocks older than 50 million years.
c. Subduction remelts oceanic rock and most has been destroyed of that age
d. Oceanic crust is only found at the ridges, which are mostly unsampled.
Which is good evidence for continental drift?
a. Reconstructions of the orientation of ancient landmasses using magnetic minerals
b. The fit of continents much like a jigsaw puzzle
c. Matches of specific geological elements from different continents, such as faults d. All of
the above
