Ocean Currents Science 6-B
1:B - Heat from the sun causes patterns
2:A - The equator receives direct sunlight.
3:A - Currents tend to move clockwise
4:C - Areas see big temperature & precipitation changes

Why do warm ocean currents begin at the equator?(1 point)
Responses
The equator receives more direct and intense sunlight, warming the water.
