a)

Coriolis Effect

b)

Upwelling

c)

Gyre

d)

Downwelling

2.

The rotation of the earth that influences ocean winds and currents

a)

Coriolis Effect

b)

Upwelling

c)

Gyre

d)

Downwelling

3.

Occurs when water pulls away from the surface and nutrient rich water from the deep is brought to the surface

a)

Coriolis Effect

b)

Upwelling

c)

Gyre

d)

Downwelling

4.

Occurs when water piles up and sinks, trapping nutrients on the seafloor

a)

Coriolis Effect

b)

Upwelling

c)

Gyre

d)

Downwelling

5.

Dangers of discarded fishing nets in the oceans

a)

Sea turtles eat them, thinking they are jellyfish. Since they cannot digest the material, they starve to death.

b)

Oxygen-breathing marine life, like sea turtles, seals and dolphins, become entangled and drowned

c)

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

6.

Dangers of discarded plastic bags in the oceans

a)

Sea turtles eat them, thinking they are jellyfish. Since they cannot digest the material, they starve to death.

b)

Oxygen-breathing marine life, like sea turtles, seals and dolphins, become entangled and drowned

c)

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

7.

Dangers of microplastics in the oceans

a)

Sea turtles eat them, thinking they are jellyfish. Since they cannot digest the material, they starve to death.

b)

Oxygen-breathing marine life, like sea turtles, seals and dolphins, become entangled and drowned

c)

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

8.

A substance that can be decomposed by bacteria or natural processes is considered....

a)

Photodegradable

b)

Biodegradable

c)

Entangled

d)

Photobiogradable

9.

A substance that is broken down into smaller bits by the exposure to sunlight is considered...

a)

Photodegradable

b)

Biodegradable

c)

Entangled

d)

Photobiogradable

10.

The principle drivers of currents in the South Pacific are the ...

a)

Density differences

b)

Trade Winds

c)

Salinity differences between water masses

d)

Downwellings

11.

The effects of upwellings

a)

Nutrients are brought up from the seafloor, creating high productivity and increasing biodiversity

b)

Nutrient poor water sinks and traps nutrients on the bottom of the ocean

c)

Plastic bits are eaten by fish, who's stomachs fill and they starve

d)

Trash is trapped by the circular motion of water "hilling up" in the center

12.

Which of the following are dangers of microplastics in the environment?

a)

Plastics and toxins enter into the food chain

b)

Barnacles starve because plastic replaces a large amount of plankton

c)

Baby birds starve as they are fed bits of plastic instead of real food.

d)

All of the answers are correct

13.

During an El Nino, trade winds are typically...

a)

about average

b)

stronger

c)

weaker

14.

The picture represents a(n) ___ event.

a)

El Nino

b)

La Nina

c)

Non-El Nino (normal trade winds)

15.

The picture represents a(n) ___ event.

a)

El Nino

b)

La Nina

c)

Non-El Nino (normal conditions)

16.

Why do the fisherman of Peru and South America not welcome a strong El Nino?

a)

El Nino poisons the fish, which destroys the fishing industry

b)

El Nino causes strong winds and currents which move fish westward

c)

El Nino brings cold water to the surface which kills the base of the food chain

d)

El Nino decreases upwelling and therefore less nutrients are available to support the food chain

17.

The regular movements of water far below the surface of the oceans are called

a)

Warm Currents

b)

Deep Currents

c)

Surface Currents

d)

Surface Currents

18.

colder and less dense

b)

warmer and less dense

c)

warmer and more dense

d)

colder and more dense
