Answer to Question 1

The two types of continental margin are passive and active. Nearly the entire Atlantic Ocean and a large portion of the Indian Ocean are surrounded by passive continental margins. By contrast, most of the Pacific Ocean is bordered by active continental margins (subduction zones). Passive margins are where flooded extensions of the continent merge into oceanic crust, and there is active deposition. Active margins are too tectonically active with subduction for sediments to accumulatethey form the Ring of Fire with active volcanism.
