Now that we have traveled through the Global Ocean Conveyor Belt, let's summarize the major parts by matching the description to the appropriate image.

Draggable item		Corresponding Item
The current is "recharged" as it travels along the coast of Antarctica and picks up more cold, salty, dense water.
The now-warmed surface waters continue circulating around the globe. They eventually return to the North Atlantic where the cycle begins again.
Cold, salty, dense water sinks at the Earth's northern polar region and heads south along the western Atlantic basin.
The main current splits into two sections, one traveling northward into the Indian Ocean, while the other heads up into the western Pacific.
The two branches of the current warm and rise as they travel northward, then loop back around southward and westward.

Below is a model of the Northern Atlantic Ocean.
Identify the location where water becomes very dense due to low temperature and high salt concentration.

Reflect on your understanding of the learning objectives:

	Analyze the relationship between corals and algae and the impact coral bleaching has on biodiversity
	Predict how increased acidity in the oceans affects corals and shellfish

Reflect on your mastery of the success criteria:

	Explain how corals and algae help each other and identify the effects of corals losing their algae
	Explain the effect of lower pH on coral skeletons and shellfish

Why would seawater be saltier near the Arctic and Antarctic?

When seawater freezes, what happens to the salt particles?

Let's imagine we could hop a ride on the Global Ocean Conveyor Belt and hit all of the major stops.

Let's start in the North Atlantic

The white arrows indicate the direction and depth of water flow.
Observe the water in the North Atlantic off the coast of Greenland.
What happens as the water begins to move south?

The cold, salty, dense water continues south towards Antarctica.
Why don't deep ocean currents rise to the surface at the Equator?

Select the areas of upwelling (where deep ocean water rises to the surface)

Now that we have traveled through the Global Ocean Conveyor Belt, let's summarize the major parts by matching the description to the appropriate image.

Below is a model of the Northern Atlantic Ocean.
Identify the location where water becomes very dense due to low temperature and high salt concentration.

Blue food coloring was added so we can see how the water molecules are moving.
Which way does the water move when it is cooled by the ice?

Which way does the water move when it runs into the end of the tank by the heat lamp?
