NGSS.MS-ESS2-3

a continuous elevated zone on the floor of all the major ocean basins and varying in width from 1000-4000km; the rifts at the crests represent divergent plate boundaries

the region where an oceanic plate sinks down into the asthenosphere at a convergent boundary, usually between continental and oceanic plates

• deep ocean trench

• rift valley

• oceanic ridge

• subduction zone
