Ocean Ecosystems:

Intertidal, Neritic, and Deep Ocean ZonesSlide2

Warm Up & Spiral

November 4

How are surface currents created?

How are deep ocean currents created?

What are 2 factors that affect the density of water?

What is upwelling?

Objectioves

: 8.E.1.1/1.2

-TSWU that the ocean is divided up into smaller ecosystems including coral reefs, kelp forests, deep ocean,

neritic

zone, and surface zone.

-TSWU the types of organisms that live in each marine ecosystem.

Essential Question:

-What types of organisms can be found in each marine ecosystem?

-What types of ecosystems can be found in the ocean? Slide3

Warm Up November 4

Describe what happens in the ocean during upwelling.

What causes upwelling?

Objectives: 8.E.1.2

-TSWU the hydrosphere including the differences and similarities between the intertidal,

neritic

, and deep ocean zones.

Essential Question:

-What is the difference between the intertidal,

neritic

, and deep ocean zones? Slide4

What is Upwelling?

Winds blowing across the ocean’s surface pushes water away.

Cold water rises from deep in the ocean.

The cold water brings nutrients from the deep ocean to the surface.

Why is upwelling good

for organisms at the

oceans surface? Slide5

Once water leaves the estuary,

it heads out to the oceanSlide6

Oceans make up about 70% of our Earth surface.Slide7

As salinity increases,

water’s density INCREASES.Slide8

We should already know which is more dense, solid water or liquid water.

Which is more dense solid water or liquid water????Slide9

But is cold water more or less dense than warm water?Slide10

Is cold water more dense than warm water?

While ice is

LESS

dense than liquid water, cold water is

MORE

dense than warm water.Slide11

Answer ANALYSIS QUESTIONS:

Two (2) ways to change the density of ocean water are: ________________ & _______________

The more salt dissolved in water, the ________ dense this ocean water is.

The colder liquid water gets, the __________ dense the ocean gets.

All our oceans are connected by surface & deep water currents.

Surface & deep currents move all Earth’s salt water aroundSlide14

All our oceans are connected by surface & deep water currents.

Surface & deep currents move all Earth’s salt water aroundSlide15

Deep water currents are driven by changes in ocean water density.

By changes in salinity and temperature

make some ocean water sink or rise creating deep ocean currents!Slide16

Deep water currents are driven by changes in ocean water density.

By changes in salinity and temperature

make some ocean water sink or rise creating deep ocean currents!Slide17

Without currents

moving salt water around our planet, our daily temperatures would be much more EXTREME.Slide18

Surface & deep currents

moderates

temperatures across the globe!

Why?

Because salt water doesn’t FREEZE or EVAPORATE as fast as fresh water!

No big swingsSlide19

Why are oceans SALTY?

Eroding land

Volcanic emissions

Atmospheric

deposition

Biological & chemical reactions at the sea floorSlide20

Slide31

Our ocean has

many

ecosystems:

WE WILL BE LOOKING AT EACH OF THESE ECOSYSTEMS

OVER THE NEXT FEW DAYS, BUT 1

ST

LETS LOOK AT SOME

SAMPLES OF LIFE…Slide32

Our ocean has

many

ecosystems

but

:

The ocean has 3 main ecosystemsSlide33

Our ocean has

many

ecosystems:

3 Main zones in the ocean include:

1. SHORELINE = INTERTIDAL ZONE

2. CONTINENTAL SHELF = NERITIC ZONE

3. DEEP ZONE = BENTHIC ZONESlide34

Our ocean has

many

ecosystems:

3 Main zones in the ocean include:

Intertidal Zone

1. SHORELINE = INTERTIDAL ZONE

Located along the shore

Towards the mangrove forests and salt marshes but not that far.

Located at the area between the high tide and low tide mark.

Slide35

Our ocean has

many

ecosystems:

3 Main zones in the ocean include:

Intertidal Zone

2. CONTINENTAL SHELF = NERITIC ZONE

Located along the continental shelf

Kelp forests and coral reefs are found here.

Sunlight does penetrate this zone.

Photosynthesis occurs here. Slide36

Our ocean has

many

ecosystems:

3 Main zones in the ocean include:

Intertidal Zone

3. DEEP ZONE = BENTHIC ZONE

Benthic vents are located here at the bottom of the ocean.

Photosynthesis does not occur here because NO sunlight can reach this far.

Organisms use a process known as chemosynthesis to survive at this depth.

Tube worms feed on sulfur eating bacteria here. Slide37

Ocean Life Lab

Work in your pairsSlide38

Do the following table in your notes:

Organism

Draw an illustration of the organism.

Describe the organism.

Identify the organism.

Which ocean zone does the organism live in?

Write two interesting fact about the organism.

Each pair will get a bag of ocean life and you must classify at least 5.

FILL IN YOUR TABLE COMPLETELY!Slide40

FILL IN YOUR TABLE COMPLETELY!

WHEN DONE, PICK YOUR MOST INTERESTING SPECIMEN AND PRESENT IT TO CLASS!Slide41

Clean-up….

Place your shells back onto the Zip lock bag and place in the bin.

Place the Shell guide back in the bin

Place your bins on top of your textbook. Slide42
