5
What three factors most directly affect surface currents in the oceans?
deep currents, convection currents, and surface winds
upwelling, convection, and the sun’s energy
Winds, Coriolis effect, and continental deflection
Gases, nutrients, and wind
6
How do warm ocean currents affect climate?
Warm currents absorb heat, cooling the air and climate.
Warm currents have no effect on climate.
Warm currents release heat, warming the air and climate.
Only cold currents effect the climate.
7
How are deep currents formed?
warm water dissolves more minerals and gases making it sink
heating of surface water by the sun causing upwelling.
Warm water sinks, cold water rises
cooler water at poles sinks, warmer water at equator rises
8
When upwelling takes place, which of the following happens?
Nutrients are brought to the surface.
Cold water sinks to the bottom
The Earth's rotation affects a current
The number of animals decreases.
9
Wind is caused by

Coriolis Effect
The sun
Surface currents
10
Which of the following best describes the movement of heat energy in the ocean?

11
What do currents transport?
Energy
Heat
Matter
All of these
12
Surface currents are mainly caused by
