Ocean water plays an indispensable role in supporting life. The great ocean basins hold about 300 million cubic miles of water. From this vast amount, about 80,000 cubic miles of water are sucked into the atmosphere each year by evaporation and returned by precipitation and drainage to the ocean. More than 24,000 cubic miles of rain descend annually upon the continents. This vast amount is required to replenish the lakes and streams, springs and water tables on which all flora and fauna are dependent. Thus, the hydrosphere permits organic existence.
The hydrosphere has strange characteristics because water has properties unlike those of any other liquid. One anomaly is that water upon freezing expands by about 9 percent, whereas most liquids contract on cooling. For this reason, ice floats on water bodies instead of sinking to the bottom. If the ice sank, the hydrosphere would soon be frozen solidly, except for a thin layer of surface melt water during the summer season. Thus, all aquatic life would be destroyed and the interchange of warm and cold currents, which moderates climate, would be notably absent.
Another outstanding characteristic of water is that water has a heat capacity which is the highest of all liquids and solids except ammonia. This characteristic enables the oceans to absorb and store vast quantities of heat, thereby often preventing climatic extremes. In addition, water dissolves more substances than any other liquid. It is this characteristic which helps make oceans a great storehouse for minerals which have been washed down from the continents. In several areas of the world these minerals are being commercially exploited. Solar evaporation of salt is widely practised, potash is extracted from the Dead Sea, and magnesium is produced from sea water along the American Gulf Coast.
Which of the following is NOT mentioned as a characteristic of water?

Thông tin:
A. “This characteristic enables the oceans to absorb and store vast quantities of heat...” (Đặc tính này cho phép các đại dương hấp thụ và lưu trữ một lượng nhiệt lớn,...)
B. “In addition, water dissolves more substances than any other liquid.” (Ngoài ra, nước hòa tan nhiều chất hơn bất kỳ chất lỏng nào khác.)
C, D. “One anomaly is that water upon freezing expands by about 9 percent, whereas most liquids contract on cooling.” (Một điều bất thường là nước khi đóng băng mở rộng khoảng 9%, trong khi hầu hết các chất lỏng đều co lại khi làm mát.) => Câu D đúng nhưng câu C sai. Nước không có lại mà là các chất lỏng khác
