000 YEARS. FLOATING ON THE OCEANS EVERY YEAR ARE 7,659 TRILLION METR...

1,000 years. Floating on the oceans every year are 7,659 trillion metric tons of iceencased in 10,000 icebergs that break away from the polar ice caps, more than ninetypercent of them from Antarctica.(B)Huge glaciers that stretch over the shallow continental shelf give birth to icebergsthroughout the year. Icebergs are not like sea ice, which is formed when the sea itselffreezes; rather, they are formed entirely on land, breaking off when glaciers spread overthe sea. As they drift away from the polar region, icebergs sometimes move mysteriouslyin a direction opposite to the wind, pulled by subsurface currents. Because they meltmore slowly than smaller pieces of ice, icebergs have been known to drift as far north as35 degrees south of the equator in the Atlantic Ocean.(C)The difficulty arises in other technical matters, such as the prevention of rapid melting inwarmer climates and the funneling of fresh water to shore in great volume. But even ifthe icebergs lost half of their volume in towing, the water they could provide would befar cheaper thanthatproduced by desalination, or removing salt from water.(D)Question 43: What is the main topic of the passage?A. The movement of glaciers B. Icebergs as a source of fresh waterC. Future water shortages D.

Towing icebergs to dry areas is economically possibleB. Desalination of water is the best way to obtain drinking waterC. Using water from icebergs is a very short-term solution to water shortagesD.
