Ocean Cross-section

  • Continental shelf- the continuation of the continent into the ocean.
  • slope- the abrupt drop-off from the continental shelf.
  • rise- the accumulation of material falling off the slope.
  • abyssal plain- the deepest part of the ocean. The oldest and densest basaltic rock.
  • mid-ocean ridge- divergent boundary, magma flows onto the ocean floor here creating new crust.
