Ocean Currents Flashcards
1
Q
sun hits earth most directly at
A
equator
2
Q
surface currents
A
- wind
- Coriolis effect
- position of land masses (bumpers)
3
Q
deep currents
A
•density differences
•temperature + salinity
-relationship is high to low

A
equator
8
Q
rotates clockwise in the
A
northern hemisphere
9

southern hemisphere
10
Q
water absorbs
A
heat energy
11
Q
ocean currents take the heat energy and because of evaporation
A
transport it all over the globe
12
Q
earth rotates
A
counter-clockwise
13
Q
salinity
A
amount of salt in water
14
Q
warm water at the equator creating a difference in ocean temp between
A
the equator (warm) and the poles (cold)
15
Q
ocean current
A
large streams of moving water that flow within the ocean (circulate heat)
