What is not thought to have an effect on the formation of submarine canyons?
a. The sea level
b. Turbidity currents
c. Earthquakes
d. Geothermal heating
ANS: D
The sea level has an effect on submarine canyons. When the sea level decreases, an erosion can create
a canyon especially near rivers. When the sea level rises again the canyon remains. Turbidity currents
create movements of sediments that can cut into a canyon. Earthquakes can also shake loose boulders
and sand that rush down the edge of the shelf and create submarine canyons. Information can be found
in the section Continental Margins May Be Active or Passive.
