43. What seems to determine whether a current carries warm or cold water? Explain why this is so. Is this answer correct. A=Trueor B=False .Warm water currents are carried from the equator to the poles. The sun’s rays are strike the Earth directly at the equator (they are more concentrated) and so, it warms up the water in this area. Cold water currents are carried from the poles to the equator. The sun’s rays strike the Earth at a low angle at the poles (they are spread out) and so, the water is cold in this area.
