最终冰川会沿着裂缝断开形成一座新的冰山，这样的事情属于正常现象。
Eventually the ice will break off at the crack forming a new iceberg.
McCarty和Foecke指出，当泰坦尼克号撞上冰山时，安装在船头脆弱的铁铆钉破裂开来，船体出现裂缝，加速了泰坦尼克号的消亡。
When the Titanic hit the iceberg, McCarty and Foecke say, the weaker iron rivets in the bow popped, opening seams in the hull—and hurrying the ship's demise.
上升的温度可能造成冰山的形成，通过削弱冰川，造成更多裂缝和使冰雪更可能碎落。
The rising temperature may be causing more icebergs to form by weakening the glaciers causing more cracks and making ice more likely to break off.
