托福阅读文本:

Glaciers are large masses of ice on land that show evidence of past or present movement. They

grow by the gradual transformation of snow into glacier ice.

A fresh snowfall is a fluffy mass of loosely packed snowflakes, small delicate ice crystals

grown in the atmosphere. As the snow ages on the ground for weeks or months, the crystals shrink

and become more compact, and the whole mass becomes squeezed together into a more dense

form, granular snow. As new snow falls and buries the older snow, the layers of granular snow

further compact to form firm, a much denser kind of snow, usually a year or more old, which has

little pore space. Further burial and slow cementation — a process by which crystals become

bound together in a mosaic of intergrown ice crystals — finally produce solid glacial ice. In this

process of recrystallization, the growth of new crystals at the expense of old ones, the percentage

of air is reduced from about 90 percent for snowflakes to less than 20 percent for glacier ice. The

whole process may take as little as a few years, but more likely ten or twenty years or longer. The

snow is usually many meters deep by the time the lower layers are converted into ice.

In cold glaciers those formed in the coldest regions of the Earth, the entire mass of ice is at

temperatures below the melting point and no free water exists. In temperate glaciers, the ice is at

the melting point at every pressure level within the glacier, and free water is present as small drops

or as larger accumulations in tunnels within or beneath the ice.

Formation of a glacier is complete when ice has accumulated to a thickness (and thus weight)

sufficient to make it move slowly under pressure, in much the same way that solid rock deep

within the Earth can change shape without breaking. Once that point is reached, the ice flows

downhill, either as a tongue of ice filling a valley or as thick ice cap that flows out in directions

from the highest central area where the most snow accumulates. The trip down leads to the

eventual melting of ice.
