Question

Icebergs are among nature's most spectacutar creations, and yet most people have never
spen one. A vague air of mystery envelops them. They come into being somewhere in faraway.
ingid waters, and thunderous noise and splashing turbulence, which in most cases no one
hans or sees. They ex st only a short time and then slowly waste away just a unnoticed
Objects of sheest beauty, hey have been called. Appearing in an endless varety of
shapes they may be dazzingly white, or they may be glassy blue, groun or purple, tinted fantly
or in darker hues. They are gracefutstately, Inspiring-in calm, sunlit seas
But they are also called inghtening and dangerous, and that they are in the night in the
fog and in stoms. Even in clear weather one is wise to stay a safe distance away from them.
Most of their bulk is hidden below the water, so their undenwater parts may extend out far
beyond the visible top. Also, they may roll over unexpectedy,chuming the waters around them
Icebergs are parts of glaciers that break oft, drift into the water, float about awhile, and
finally melt loebergs afloat today are made of snowflakes that have fallen over long ages of
time. They embody shows that drifted down hundreds or many thousands, or in some cases
maybe a million years ago. The snows fel in poiar regions and on cold mountains, where they
molted only a tate or not at all, and so collected to great depths over the years and centures
As each year's snow acoumulation lay on the surface, evaporation and melting caused
the snowflakes slowly to lose their feathery points and become tiny grains of loe. When now
snow foll on top of the old, it too tumed to icy grains. So blankets of snow and ice grains
mounted layer upon layer and were of such great thickness that the weight of the upper layers
compressed the lower ones. With time and pressure from above, the many small ce grains
joined and changed to larger crystals, and eventually the deeper crystals merged into a solid
mass of ice
in line 23 the expression " from above" refers to

Answer 1

Answer:

Here the "from above" refers to the pressure coming from above . During the ice age times huge masses of ice covered earth in blanket after blankets. Thus the old deposited blankets of ice joined with other ice blankets below and formed some crustals as written in the paragraph due to heavy pressure from the above blankets of ice.
