Chapter 3
Older lithosphere is destroyed in association with:
deep-sea trenches
New lithosphere is produced in association with:
oceanic ridges
Along the margins of the Pacific are found most of Earth's:
oceanic trenches.
With respect to mid-ocean ridges, transform faults are:
perpendicular to the ridge axis.
Volcanic peaks on the deep-ocean floor with conical tops are called:
seamounts
Passive continental margins are characterized by all of the following except:
shallow coastal waters. *deep-sea trenches. thick sediment accumulation. very little volcanic and earthquake activity. broad continental shelves.
The correct order of seafloor features from the coast to the mid-ocean ridge is:
shelf, slope, rise, abyssal plain.
Warm-water (From 30°C to 350°C) hydrothermal vents form:
white smokers
Submarine canyons were most likely formed by:
erosion by turbidity currents
Characteristics of active continental margins include all of the following except:
*broad continental shelves. deep-sea trenches. volcanic and earthquake activity. thin sediment accumulation. chains of islands.
