Now researchers have created a map of the world's seafloor that should help researchers estimate seafloor depths for that huge unknown area, as well as enhance oceanographic research on remote ocean basins and underwater ridges known as oceanic spreading
During Phases 1 and 2, divergent kinematic velocity boundary conditions initiate continental rifting followed by oceanic spreading
and the self- consistent growth of rifted continental margins and oceanic lithosphere.

For northwestern South America, plate tectonic stress plays out notably in the ocean-continent, and ocean-ocean and continent-continent plate collision zones, and also along oceanic spreading
ridges and transform faults.
