◦ at the seaward edge of a deep ocean trench
◦ between an abyssal plain and continental slope
◦ at the top of the continental slope
◦ at the top of a mid-ocean ridge
Question 2
What is the difference between an active continental margin and a passive continental margin?
◦ A passive margin is passively carried along by plate tectonics in a transform system, like the San Andreas whereas an active margin is a trench.
◦ An active margin has earthquakes whereas a passive margin has quiet erupting (aka passive) volcanoes.
◦ A passive margin is the site of an ancient continental rift, left behind when seafloor spreading moved offshore, whereas an active margin is an active plate boundary.
◦ An active margin receives large amounts of sediment whereas a passive margin is sediment starved.
