Answer to Question 1

A

Answer to Question 2

A passive margin is not a plate boundary but a part of the same plate as the adjoining oceanic crust. In the quiet environment, deposition of sediment on the continental shelf is producing a thick wedge of shallow-water sandstones, limestones, and shales that pile up because there is no destruction by a subduction zone. The East Coast of North America is an example of a passive continental margin.
