Question

how does water temperature affect the tendency of ocean currents to flow away from the equator?
the cooler winter temperature at the equator lowers the density of the water.
the cooler winter temperature at the equator raises the density of the water.
the warmer temperature at the equator lowers the density of the water.
the warmer temperature at the equator raises the density of the water.

Explanation:

Water density is inversely related to temperature. Cooler water is denser. At the equator, warmer water (lower density) is less likely to flow away compared to cooler (higher density) water which has a greater tendency to move.

Answer:

The cooler winter temperature at the equator lowers the density of the water.
