1 FridayStarter: Yesterday we discussed photic vs. aphotic oceanic zones. What is the difference between the two zones? List plants/animals found in each zone.
3 Oceanic ZonesSeveral factors used to divide the ocean in to distinct life marine zoneslight availabilitydistance from shorewater depth
4 Zones of Light Availability photic (light) zone: upper part of the ocean where light penetrateseuphotic zone is the topmost part of the ocean where light is strongestaphotic zone: lower part of the ocean where very little or no light penetrates
8 Aphotic Zone no living plants high pressure, low temperatures animals survive by eating detritus or other animalsanimals must adapt to living with no light
9 Zones: Distance from the Shore intertidal zone: where land an ocean overlap neritic zone: seaward from the low tide line, the continental shelf out to the shelf break oceanic zone: beyond the continental shelf
13 Oceanic Zone larger creatures life decreases with increasing depth widest array of life (because it is a very broad area)
14 Animals of the Oceanic Zone Name some animals found in this zone.
15 Water Depth pelagic zone: open ocean of any depth benthic zone: includes any sea bottom surfaceabyssal zone: subdivision of benthic zone;deepextremely high water pressurelow temperaturesWhat sort of organisms do youexpect to find in this zone?
17 Benthic Zone low oxygenation of water low temperatures animals here feed on detritus or other animalslittle or no plant life (depending on depth of water)CHECKPOINT: Why is there little orno plant life?
22 Tuesday 2-3-15 Oceanic Zones Murals Groups of three to four peopleOnce your group is chosen, see Mrs. Slusher for topicWe will be making a mural or work of art to be hung on the wallRequired info:Name and description of zoneSeveral animals found thereFacts about that zonePicturesTURN THEM IN TO ME AT MYDESK FOR IMMEDIATE GRADING!
