clockwise
200
What percentage of fish species were fully exploited in 1999?

200
Name the coloration pattern:
dark on top (dorsal side) and light on the bottom (ventral side)
Countershading

What characterizes an El Nino year in North America?
The Equatorial wind dies and warm water stays on the east side of the ocean and brings warm rains and limits upwelling and limits fish populations

Name one feature of a transverse current
They travel W-E or E-W
They link Eastern and Western Boundary Currents
They include Equatorial Currents or Equatorial Counter Currents
300
What human problem lead scientists to a better understanding of gyres?
Spilled rubber ducks recovered all over the world
Spilled shipment of Nike shoes recovered across the Northern Hemisphere
300
Name one policy or action that can be taken to reduce the likelihood of overfishing.
Preserve fish habitats
Avoid Bycatch
Strong Illegal Fishing Enforcement
Encourage Aquaculture

Which ways do the winds in typhoons (hurricanes) spin in the southern hemisphere?
counter clockwise
400
What is one feature you can use to tell the difference between bony fish and cartilage fish?
Cartilage Fish have a longer top half of their caudal fin
Cartilage Fish do not have a pelvic fin
Bony fish have a swim bladder and cartilage fish has a fatty liver
400
Name the one major current that is not a gyre.

400
What is the percentage of over exploited fish populations in 2004?

400
Why do Earth's winds appear to bend?
The Coriolis Effect
The Earth is spinning so it only looks like the wind is bending from
500
A storm that develops over warm water due to the weakening of equatorial winds and lower atmospheric pressure that is characterized by strong winds creating a circular eye and absorbs lots of water and pushes storm surge towards coastal communities
Hurricanes
500
