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:
Convergent boundaries can be of three types: Subduction demonstration. Ocean-Ocean Convergence: If the plates moving toward each other are both made of oceanic crust, one of the plates will move downward, or subduct, under the other plate.This is called a subduction zone.his relative movement of the plates creates varying conditions at the plate edges, or boundaries. Geologists describe three basic types of plate boundaries: divergent boundaries, convergent boundaries, and transform boundaries.
