This event may have also influenced the structure of the Mid-Atlantic Ridge, a vast underwater mountain system running down the center of the Atlantic Ocean.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A recent study published in the Journal of Geophysical Research: Solid Earth sheds new light on the formation of the East Coast of the United States\u2014a \u201cpassive margin,\u201d in geologic terms\u2014during the breakup of the supercontinent Pangea and the opening of the Atlantic Ocean around 230 million years ago.
