The best current thinking is that volatility (elements and compounds,including water,vaporize at low temperatures) were released from the solid phase as the earth accreted. Thus,the earth and its oceans and atmosphere grew together.

• 当前最通行的观点是挥发物(元素和化合物，包括低温下蒸发的水)在地球增生形成时的固体阶段就被释放出来，然后地球、海洋和大气逐渐连成一个整体。
