Câu hỏi:
Which of the following is NOT a result of the formation of ocean ice?
- A. The surrounding water sinks
- B. The water becomes denser
- C. The salt remains in the water
- D. Water salinity decreases
Lời giải tham khảo:
Đáp án đúng: D
Dẫn chứng: A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.
