Besides the normal states of surface liquid, vapor, or ice, much water exists locked in rock hundreds of miles deep in Earth's mantle.
除了表面覆盖的江湖海水，水蒸气、冰，大部分水可能被锁在地球的地幔深处。
The surface of an ice shelf gets covered by snow, but the underside is very pure ice.
以前的冰架表面覆盖着积雪，而底层的纯冰这时才露出来。
Higher air temperatures can increase surface melting, but warm ocean currents accelerate ice loss more when glaciers flow into the sea.
气温升高能够加速冰川表面的融化，但是当冰川漂移入海之后，温暖的洋流对冰雪消融发挥了更重要的推动作用。
