flow」
改寫成B提到的「a thick layer of ice」

※ 引述《chime0515 (我愛劉德華)》之銘言：
: Paragraph2: Glaciers are open systems, with snow as the system's input and
: meltwater as the system' s main output. The glacial system is governed by two
: basic climatic variables: precipitation and temperature. For a glacier to
: grow or maintain its mass, there must be sufficient snowfall to match or
: exceed the annual loss through melting, evaporation, and calving, which
: occurs when the glacier loses solid chunks as icebergs to the sea or to large
: lakes. If summer temperatures are high for too long, then all the snowfall
: from the previous winter will melt. Surplus snowfall is essential for a
: glacier to develop. A surplus allows snow to accumulate and for the pressure
: of snow accumulated over the years to transform buried snow into glacial ice
: with a depth great enough for the ice to flow. Glaciers are sometimes
: classified by temperature as faster-flowing temperate glaciers or as
: slower-flowing polar glaciers.
: 6. Paragraph 2 implies that which of the following conditions produces the
: fastest moving glaciers?
: ○A climate characteristic of the polar regions
: ○A thick layer of ice in a temperate climate F Long,
: ○Warm summers
: ○Snow, firm and ice that have been buried for several years
: 答案為B, 不過從最後一句看, 我覺得答案C比較合理耶
: 謝謝解答!
