True or False: There is as much water on Earth now as there was millions of years ago

Answer 1

This is true. As a whole, the amount of water has not changed significantly over the course of the history of the Earth. The amount of liquid water might have changed but total water has not. We have gone through periods of freezing where the water has become ice and then melted later. Early in Earth's formation where there was little to no water on the surface the water molecules were still present trapped in the magma that the Earth was formed from and it was this trapped water that escaped, cooled and ultimately condensed to form rain and eventually our oceans.
