उत्तर
- Most of the water on Earth came from water vapour released from the Earth’s interior by volcanic activity during its early formation.
- As the Earth cooled, this water vapour condensed into rain and collected in low-lying areas, gradually forming oceans and seas. Water-rich asteroids and comets may also have added some water.
