Question

Quizplus · Accepted Answer

A passive margin forms when a continent is separated from a diverging plate boundary, leaving behind an area of continental crust that is not actively being deformed. An active margin is a location where two tectonic plates are actively moving towards each other, resulting in geologic activity such as earthquakes and volcanoes. Therefore, the best answer is B.
