Marine Provinces

Shelf – slope – rise Abyssal plain Mid-ocean ridges Deep sea trenches Submarine canyons Abyssal plain Seamounts and guyots Mid-ocean ridges Fracture zones, transform faults Hydrothermal vents Deep sea trenches

Shelf, slope, rise

Note variable width of shelf and location of submarine canyons

Getting sediment down to the continental rise

Submarine cable Breaks in canyon

Sediment pouring down canyon

Found on abyssal plains

Location of mid-ocean ridges Note fracture zones and transform faults

Formation of hydrothermal vents

Black smoker

ALVIN

Tube worms at smoker

Ridges, transform faults, fracture zones Transform faults offset ridge segments Fracture zones are extensions of transform faults Draw relationships and relative motions

Black lines = center of ridges Offsets = transform faults Long red lines = fracture zones

Location of trenches

Continental – oceanic convergent plate boundary Many volcanoes parallel trenches Ring of Fire around Pacific
