Currents Flashcards
1
Q
What drives currents?
A
Greater the wind speed the greater the friction force and the greater the surface current
2
Q
What is the effect of wind to surface transmit
A
decreases as a result of upper ocean internal friction
3
Q
What is the result of internal friction?
A
Turbulence
4
Q
What does internal friction do?
A
Transmits motion at the surface to deeper levels
5
Q
What is the result from transmits motion
A
Ekman spiral
6
Q
What does the Ekman spiral cause?
A
Horizontal and vertical water movement
7
Q
What is divergence?
A
Drawing apart the Deeper water, rises to replacing the water removed
8
Q
What can the divergence do?
A
Lower pressure wind system and rise on thermocline
9

A
Cool water flowing hurricane and cyclones
10
Q
What does upwelling do
A
Cold blodiversity oz lister cold
