Warm Up, November 4th, 2014 What are the benefits of one of you teaching class? What are the cons? (educational answers only) What was the purpose of yesterday’s activity/lab? What would a creature that lives in the intertidal zone need to be adapted to in order to live there? What about a creature in the neritic zone? Deep?

- The submerged border of a continent that slopes gradually down.
Continental Shelf* - The submerged border of a continent that slopes gradually down.
4
Phytoplankton* - Microscopic organisms that inhabit the upper, sunny layers of oceans and most fresh water. Phytoplankton produce most of the world’s oxygen.
5
Why are oceans SALTY? Eroding land - salt in rocks.
6
Why are oceans SALTY? Eroding land Volcanic emissions
8
Why are oceans SALTY? Eroding land Volcanic emissions
Atmospheric Deposition (All sorts of stuff gets up in our air and comes back down .)
9
Why are oceans SALTY?* Eroding land Volcanic emissions
Atmospheric deposition Biological and chemical reactions on the sea floor
10
Brain Pop - Oceans
11
Our ocean has 3 ecosystems:
Intertidal Zone (aka…littoral zone aka…shoreline)
12
Our ocean has 3 ecosystems:
Shoreline (aka…littoral zone…intertidal zone) Neritic zone (aka…Nemo/Sponge Bob territory…)
13
Our ocean has 3 ecosystems:
Shoreline (aka…littoral zone…intertidal zone) Neritic zone (aka…continental shelf)
14
Our ocean has 3 ecosystems:
Shoreline (aka…littoral zone…intertidal zone) Neritic zone (aka…continental shelf)
15
Our ocean has 3 ecosystems:
Shoreline (aka…littoral zone…intertidal zone) Neritic zone (aka…continental shelf) Deep ocean (aka…benthic zone)
16
Our ocean has 3 ecosystems:
Shoreline (aka…littoral zone…intertidal zone) Neritic zone (aka…continental shelf) Deep ocean (aka…benthic zone)
17
Our ocean has 3 ecosystems:
Shoreline (aka…littoral zone…intertidal zone) Neritic zone (aka…continental shelf) Deep ocean
18
The Three Zones – Intertidal Zone*
Animals and plants must be able to live in wet and dry conditions Zone with most sunlight
19
Because of the tides, waves, & predation, shoreline creatures can fly high or dig down low. Or wait it out…
20
What causes the tides?
21
What causes the tides? The tides are caused by the Sun and the moon having a tug-o-war with the Earth as rope!
22
The tides are the sun & the moon having a tug-o-war with the earth (gravitationally speaking).
23
Why doesn’t the sun pull the earth hard enough to negate the moon
Why doesn’t the sun pull the earth hard enough to negate the moon? The sun has much more mass after all…
24
The Three Zones Shoreline…Littoral Zone…Intertidal Zone Neritic Zone Deep Zone
25
The Three Zones – Neritic Zone*
Home to unique habitats: kelp forests and coral reefs Zone with most life
26
The Three Zones Shoreline…Littoral Zone…Intertidal Zone Neritic Zone Deep Zone…Oceanic Zone…Benthic Zone
27
The Three Zones – Deep Zone*
High pressure, no light Zone with most water (65%)
28
Bill Nye - Oceanography
