The volcanic edifice is an elongated, flat cone of about 1650 m height. They took shape during a period of intense plate tectonic activity around 170 to 40 million years ago. Natural or human-made structures that cross a transform boundary are offset split into pieces and carried in opposite directions. Learn the mountain definition and discover how mountains are formed. The Laramide orogeny period, also known as the mountain-building period, saw the Farallon ocean plate move underneath the North American tectonic plate at a low angle. Similar patterns apply to the Rocky Mountains, but they are significantly different in having a much longer history of high elevation habitat. Study Guide Answer Key: Questions 1.
