Oceans

Oceans 1

100

regular rise and fall of the oceans surface caused by gravitational pull of the moon.

Tides

200

This type of ocean movement is caused by wind and the rotation of earth. 

Surface currents

300

DOUBLE JEOPARDY- CHALLENGE!!!! 

Look at the picture Miss Dorn is going to show you. What is in the ocean water that starts flowing into the river water?

SALT - rivers are freshwater, meaning there is no salt in them. But when ocean water meets the beginning of a river, the salt sinks to the bottom of the river. 

400

This is the word for how much salt is in the ocean at various depths.

Salinity

500

This ocean movement moves in an up and down pattern. They're caused by the friction of wind on the water.

Waves

Oceans 2

100

Current that goes around the US and over to Europe keeping their temperatures mild

Gulf Stream

200

How many times a day tides happen

twice (2) - 2 times each

300

This increases the deeper you go into the ocean

pressure

400

DOUBLE JEOPARDY!!! 

Challenge: this is the name of the rotating currents on the surface of the ocean. 

gyres

500

Continuous regular pattern of water flow in the ocean

current

Oceans 3

100

Another term for deep water currents. Think of the cycle. 

Convection currents. 

200

These are the 2 types of currents. 

Surface and deep water.

300

This is what causes deep water currents (more than one thing!)

Temperature decreases, salinity increases

400

This happens to the water as temperature decreases and salinity increases. 

It sinks/heavier/more dense

500

DOUBLE JEOPARDY!!!!!! 

You have two cups of water. Cup A is 70 degrees and Cup B is 20 degrees. You pour both cups into a bucket that is 40 degrees. What do you think happens to the water from both cups?

Water from cup A rises while water from cup B sinks.
