What term refers to the saltiness of water? (You can't say "um"!)
Salinity
What are ocean currents? (You can't say "um"!)
Ocean currents are large volumes of water flowing in a certain direction.
What separates the Northern Hemisphere from the Southern Hemisphere? (You can't say "um"!)
The equator separates the Northern and Southern Hemispheres.
What is a gyre? (You can't say "um"!)
A gyre is a large system of rotating ocean currents.
The vertical motion of water towards the ocean's surface is known as _____________.
Upwelling
DOUBLE JEOPARDY RIDDLE: If you’re running in a race and you pass the person in second place, what place are you in?
Second place!
In what direction do surface currents move? (You can't say "um"!)
These currents are driven by the wind. (You can't say "um"!)
Surface currents are driven by the wind.
What two things affect the density of water? (You can't say "um"!)
Temperature and salinity affect the density of water.
Surface currents create large systems of rotating water in the ocean called ______________.
Surface currents create large systems of rotating water in the ocean called gyres.
DOUBLE JEOPARDY RIDDLE: There’s a one-story house in which everything is yellow. Yellow walls, yellow doors, yellow furniture. What color are the stairs?
There aren’t any - it’s a one-story house.
What direction do gyres turn in the Northern Hemisphere? (You can't say "um"!)

DOUBLE JEOPARDY RIDDLE: You see a boat filled with people, yet there isn’t a single person on board. How is that possible?
All the people on the boat are married.
What direction do gyres turn in the Southern Hemisphere? (You can't say "um"!)

What happens to the density of water if you decrease the temperature of the water? (You can't say "um"!)
The density of the water increases.
DOUBLE JEOPARDY RIDDLE: What can’t be put in a saucepan?
It's lid!
What causes deep ocean currents? (You can't say "um"!)
Density differences (temperature and salnity) in water cause deep ocean currents.
What is the Coriolis Effect? Explain WHAT it is and WHY it occurs. (You can't say "um"!)
The Coriolis Effect causes wind and water to move in different circular directions in the Northern and Southern hemispheres due to Earth's rotation.
Will an object that is placed in saltwater sink or float? EXPLAIN WHY. (You can't say "um"!)
Deep ocean currents follow one path around the Earth called the ___________________.
global conveyor belt
