Coastal vs. Open Sea
Coastal vs. Open Sea (Pelagic)
Euphotic
Bathyal
Abyssal
- Little to no light = no plankton, fewer organisms, slow metabolism and energy efficient
- Deep sea, highest pressure, coldest temps
- Sunlight present = photosynthesis = plankton
- 200 m
- benthic- abyssal plain

Continental shelf
Continental slope
Continental rise
- edge of a continent that is under the ocean, usually exposed during ice ages
- relatively steep transition
- gentle transition, made of accumulated sediments
