At what temperature does sea ice form in the polar oceans? a. 0°c b. -0.5°c c. -1.9°c d. -2.4°c e. -32°c

The correct answer is - C. -1.9 C degrees.

The sea ice in the polar oceans needs little lower temperatures to start forming than what it would need if it was't forming on a saline water. The freshwater starts freezing as the temperature goes bellow 0 C degrees, but that is not the case with the saline water. The saline water, because of the salt that prevents the freezing to a certain point, needs temperature of -1.9 C degrees to start freezing. Once this temperature is reached, the salt can not prevent the freezing anymore, so the water on the polar oceans starts to freeze.

the correct answer is 2 and 4

i believe your answer would be c.. : )
