WebActive continental margins are those that are tectonically active, such as along much of the Pacific coast. Active margins are marked by earthquakes, volcanoes, and mountain belts. Unlike passive margins, they lack a continental rise and abyssal plain. WebPassive continental margins develop along coastlines that are not tectonically active, including much of the Atlantic Ocean coastline.
