Where would you expect to find a garbage patch in the North Pacific Ocean?
Which layer of the ocean has the highest salinity?
Deep ocean circulation is powered by differences in density, temperature, and salinity. We call this the Great Ocean Conveyor Belt.
In the North Atlantic Ocean near Greenland, ice forms. The salty, cold water sinks and warm water replaces it.
But in recent years less ice has been forming in the North Atlantic. How will that affect the Great Ocean Conveyor Belt near Greenland?
The water will become salty and sink more .
A teacher did a demonstration with one cup of fresh water dyed yellow and one cup of salty water dyed blue.
Using a piece of cardboard between them, she arranged the yellow fresh water cup over the blue salt water cup.
What will happen when she removes the cardboard between them?

Select El Niño or La Niña, then explain how it affects conditions in the Pacific Northwest.
The effects of El Niño and La Niña have since 1950.
