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.

剩余的积雪能够让雪集成堆，且由于多年的积雪形成的压力，剩余的积雪能够让掩埋的雪变成冰川冰，这些冰川冰的厚度足以使冰块流动。

Not only do melting snow and ice flow directly into the sea, they also form torrential under-ice streams that lubricate the passage of glaciers toward the ocean.

融化的冰雪不仅直接流入大海，还在冰下形成湍流，为冰川滑向海洋大开方便之门。

While earthquakes have often been blamed for rock failures and landslides on mountain slopes, scientists also point at global temperature rises for rapid thawing of snowfields and glacial melt that can disturb the flow of snow-fed rivers.
