Although seawater is usually very salty, sea ice is practically salt-free. Why is this ? When the water temperature dips to its freezing point (about 28.6 0 F), tiny ice particles form. Salt is not part of the ice crystals’ molecular, so it is gradually released into the surrounding water. However, in extremely cold water, ice freezes rapidly, so salt cells are sometimes trapped before they are discarded. The cells then “migrate” through the ice, a process which takes up to a year. As ice crystals multiply, the water turns slushy and the surface freezes into thin sheets of ice. Wind and wave action break the sheets into pieces, put them together, and freeze them into thick solid masses of pack ice. Depending on the severity of the winter, the pack’s thickness is usually nine to ten feet. Pieces breaking from the pack present the greatest threat to ships transiting through polar water. The Arctic produces 10,000 to 50,000 icebergs annually. The amount produced in the Antarctic region is inestimable. 36- Sea ice is seen ___________ a- everywhere on the earth b- in the Arctic and Atlantic c- in the Antarctic d- in the poles of the earth 37- The temperature at which seawater frees is determined by ___________ a- low air b- salinity c- sea ice d- seawater 38- Sea ice ___________ a- contains no salt b- is usually very salty c- is more salty than seawater d- makes the temperature decrease 39- Salt can be released ___________ a- immediately after the tiny ice particles are formed b- rapidly in extremely cold water c- gradually after a long time d- slowly during the melt of the ice sea 40- Which sentence is true ? a- The thick solid masses of pack ice are formed from the ice crystals b- The pieces of ice breaking from the pack ice can be seen by ships transiting through polar water c- Every year, the icebergs produced in the poles increase d- The writer wants to say that we should go to the Antarctic to see the icebergs VII- Choose the best options 41- It’s a pity that you didn’t tell us about this. a- I wish you told us about this b- I wish you would tell us about this c- I wish you had told us about this d- I wish you have told us about this 42- My brother and I went to that school. a- I went to that school and my brother, too. b.
