Ocean Zones

ocean zones

1. intertidal--high and low tides, 2. benthic--ocean floor, 3. pelagic--ocean water (divided into neritic and oceanic provinces)

dysphotic zone

Around 1000 m where photosynthesis stops.

hadalpelagic zone

Deepest part, trenches

bathypelagic zone

Midnight zone Lightless zone of the open ocean, lying above the abyssal or bottom water, usually above 4000 m.

supralittoral zone

Splash zone, part of benthic zone

mesopelagic zone

The pelagic layer of the ocean where light can penetrate, yet without the intensity to support photosynthesis

epipelagic zone

The photic zone is confined to the: Which of the following is NOT one of the deep ocean's zones?

abyssopelagic zone

This bottom zone of the open ocean extends to the seafloor.

euphotic zone

Upper layer of a body of water through which sunlight can penetrate and support photosynthesis.

sublittoral zone

What begins where the intertidal zone ends, at the low-tide limit? It ends at the edge of the continental shelf, about 200 m below sea level. It is also more stable than the intertidal zone

benthic zone

bottom of an aquatic ecosystem; consists of sand and sediment and supports its own community of organisms

aphotic zone

dark layer of the oceans below the photic zone where sunlight does not penetrate

pelagic zone

open water above the ocean floor
