I showed up to the interview dressed to the nines, post double shot latte, and mentally prepped only to be ushered to a hallway lined with chairs and a dozen other potential applicants already waiting their turn. I knew I needed something to make me stand out if I had any chance of securing the job.
Answer 1: At plate boundaries where sea-floor spreading occurs, magma wells up to fill the space created by the plates that are moving apart. Check out this United States Geologic Survey (USGS) educational animation to see visually how it works:
Red Sea/East African Triple Junction Mid-Atlantic Ridge. At divergent plate margins, plates are moving apart and new lithosphere is being created. In the oceans, this has produced the mid ocean ridge system, which can also be described as a global range of underwater mountains.t divergent plate margins, plates are moving apart and new lithosphere is being created.
