1 1. _____ surface features of ocean floor. 2._____ slopes gently down from edge of a continent. 3. _____slopes steeply from continental shelf

2 Ocean Floor Lab (use pg in CRCT Book 1. Cut out words 2. Cut out pictures 3. Cut out definitions 4. Place words picture definition 5. Get checked for correctness 6. Glue in

3 Key Questions: 1.What is the benthic environment? 2. What is the interdial zone? 3. What is the sublittoral zone? 4. What is the bathyal zone? 5. What is the abyssal zone? 6.What is the Hadal zone? 7. What is the neritic zone? 8. What is the oceanic zone?

4 Benthic Environment- the ocean floor and the organisms that live in or on it

5 Benthic > Intertidal Zone Shallowest zone Located between high and low tide Covered by water (low tide) and exposed to air and sun (high tide) Clams, oysters, crabs

6 Benthic > Sublittoral Starts where intertidal ends and edge of continental shelf Stable temperature, water pressure, sunlight Corals

7 Benthic > Bathyal On continental slope Little sunlight or plants Sponge, sea stars, octopus

8 Benthic > Abyssal On abyssal plain No sunlight No plants Few animals Sea cucumbers, crabs, sponges, worms

9 Benthic > Hadal Located in Trenches Deepest zone No sunlight or plants Few Animals Floor of trenches Sponge, worms, clams

10 Pelagic > Neritic Zone Warm Shallow (Over the Continental Shelf) Largest concentration of marine life Fish, plankton, marine animals

11 Pelagic > Oceanic Zone Whole ocean floor except the continental shelf Deeper, Colder, More Pressure Angler fish
