Keylrieth Bellerid7.r, age ll, of Berkeley, Ill., For his question:

When and where do icebergs melt?

Chunk icebergs are forever breaking from the glaciers that dip dawn to the polar seas. With thundering roars and resounding crashes they fall into the icy sea. Since they are made of ice, they float and the tossing waves carry them away. Sooner or later they are caught and carried along by Ocean currents to warmer seas.

Icebergs from the frozen north are swept southward, and some melt in the North Pacific. Some are carried across the Atlantic by the warm Gulf Stream and melt long before they reach the shores of europe. Icebergs from Antarctica are swept around the southern seas. Here the water is eternally chilly, and they may travel long journeys before they, too, finally melt.
