Question

Quizplus · Accepted Answer

This statement is false. The hydrosphere began to form almost as soon as Earth formed, around 4.6 billion years ago, as water molecules were present in the gases that made up the planet's atmosphere. The hydrosphere continued to develop through volcanic activity, meteor impacts, and the process of outgassing.
