VI- Read the passage carefully and then choose the best answers
Sea ice is commonly found in the Arctic and Antarctic where low air and water temperature provide ideal conditions for ice formation and growth
Trang 3Salinity, the amount of salt in seawater, determines the temperature at which seawater freezes 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 0F), 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
