what causes water to become denser when it is carried to the poles by surface currents?\no increased temperature and increased salinity\no decreased temperature and decreased salinity\no increased temperature and decreased salinity\no decreased temperature and increased salinity
Answer
Brief Explanations:
Water density increases with lower temperature as the molecules slow down and pack closer together. Also, higher salinity means more dissolved salts, adding mass and thus increasing density. As water is carried to the poles by surface - currents, temperature drops and evaporation can increase salinity in some cases.
Answer:
D. decreased temperature and increased salinity
