Answer to Question 1ANS: 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.
Answer to Question 2ANS:Answer
should include:
The Coriolis effect is the deflection of moving air and water masses. This is the result of
the eastward rotation of the Earth.
In the Northern Hemisphere, moving objects move clockwise from its initial trajectory.
The Southern Hemisphere's deflection occurs to the left of counterclockwise. The
observed deflection is the result of an observers moving frame of reference on the
already spinning Earth.
The Coriolis effect is at different rates along different latitudes. Remember the Buffalo
and Quinto example. Buffalo moves slower than Quinto to maintain the same directional
position. It is dependent on the frame of reference.
The Coriolis effect deflects ocean and atmospheric movements. This shifting allows doe
global circulation of the different air density masses from the uneven solar heating of the
Earth. The most visible effect is at mid-latitudes where there is a frictionless flow of
fluids.
