The Dangers of Icebergs

By: Ameerah


Icebergs are among nature's most spectacular creations, and yet most people have never seen one. A vague air of mystery envelops them. They come into being somewhere in faraway, waters, amid thunderous noise and splashing turbulence, which in most cases no one hears or sees. They exist only for a short time and then slowly Links Of London Bracelets melt away just as unnoticed.

Objects of sheerest beauty, they have been called. Appearing in an endless variety of shapes, they may be dazzlingly white, or they may be glassy blue, green or purple, tinted faintly or in darker hues. They are grateful, stately, inspiring in calm, sunlit seas. But they are also called frightening and dangerous, and that they are in the night, in the fog, and in storms. Even in clear weather one is wise to stay at a safe distance away from them.
Most of their bilk is hidden below the visible top. Also, they may roll over unexpectedly, stirring the waters around them.

Icebergs are parts of glaciers that break of, drift into the Water, float about a while, and finally melt. Icebergs afloat today are made of snowflakes that have fallen over long ages of time. They embody snows that drifted down hundreds, or many thousands, or in some cases maybe a million years ago. The snows fell in Polar Regions and on cold mountains, where they melted only a little or not at all, and so collected to great depths over the years and centuries.

As each year's snow accumulation lay on the surface, evaporation and melting caused the snowflakes slowly fell on the top of the old; it too turned to icy grains. So blankets of snow and ice grains mounted layer upon layer and were Links Of London Charms of such great thickness that the weight of the upper layers compressed the lower ones. With time and pressure from above, the many small ice grains joined and changed to larger crystals, and eventually the deeper crystals merged into a solid mass of ice.
