Downwelling
The rotation of the earth that influences ocean winds and currents
Coriolis Effect
Upwelling
Gyre
Downwelling
Occurs when water pulls away from the surface and nutrient rich water from the deep is brought to the surface
Coriolis Effect

Dangers of discarded fishing nets in the oceans
Sea turtles eat them, thinking they are jellyfish. Since they cannot digest the material, they starve to death.
Oxygen-breathing marine life, like sea turtles, seals and dolphins, become entangled and drowned
Birds feed them to their young, causing their stomachs to fill indigestible material and they starve.
Dangers of discarded plastic bags in the oceans
Sea turtles eat them, thinking they are jellyfish. Since they cannot digest the material, they starve to death.

Birds feed them to their young, causing their stomachs to fill indigestible material and they starve.

Downwellings
The effects of upwellings
Nutrients are brought up from the seafloor, creating high productivity and increasing biodiversity
Nutrient poor water sinks and traps nutrients on the bottom of the ocean
Plastic bits are eaten by fish, who's stomachs fill and they starve
Trash is trapped by the circular motion of water "hilling up" in the center
Which of the following are dangers of microplastics in the environment?
Plastics and toxins enter into the food chain
Barnacles starve because plastic replaces a large amount of plankton
Baby birds starve as they are fed bits of plastic instead of real food.
All of the answers are correct
During an El Nino, trade winds are typically...
about average
stronger
weaker
The picture represents a(n) ___ event.
El Nino
La Nina
Non-El Nino (normal trade winds)
The picture represents a(n) ___ event.
El Nino
La Nina
Non-El Nino (normal conditions)
Why do the fisherman of Peru and South America not welcome a strong El Nino?
El Nino poisons the fish, which destroys the fishing industry
El Nino causes strong winds and currents which move fish westward
El Nino brings cold water to the surface which kills the base of the food chain
El Nino decreases upwelling and therefore less nutrients are available to support the food chain
The regular movements of water far below the surface of the oceans are called
Warm Currents
Deep Currents
Surface Currents
Surface Currents
colder and less dense
warmer and less dense
warmer and more dense
colder and more dense
