Document Summary

Toby irenshtain - lab 2 synthesis study guide. Ex: mid atlantic ridge or east pacific rise. Created by seafloor spreading and creation of new ocean crust. Close to an ocean-ocean convergent boundary on the overriding tectonic plate. Created by subduction of one tectonic plate beneath another. Faces a divergent boundary but relatively far from actual boundary. Originally created by breakup of continent and formation of new ocean basin. Deep atlantic basin between continental margin and divergent boundary. Originally created by a mid ocean ridge. Rapid spreading of the east pacific rise is wider with lower relief because warm buoyant ocean crust moves away from the spreading center further before it cools and subsides. The mid-atlantic ridge oceanic crust cools and subsides closer to the spreading center, creating a steeper and narrower ridge. Iceland is on the mid-atlantic ridge = frequent volcanoes and rift valley that runs through iceland reflects this.
