Question

In addition to comets, water for Earth's early oceans might have come from A. cyanobacteria. B. rivers. C. rain. D. volcanic eruptions

Answer 1

D Volcanic Eruptions- Volcanic out gassing to rain down to the surface and fill in the basins forming the world’s oceans.

Answer 2

The correct answer is:

D. volcanic eruptions

Explanation:

4.0 Billion Years Ago, Earth’s outside cools enough for most of the water that has accumulated in the atmosphere from comets and volcanic outgassing to rain down to the surface and fill in the basins making the world’s oceans. Explosive volcanic eruptions change the global climate largely through including sulfur, improve the salinity near the Greenland Sea, and considerably reduces static balance, which means more surface water sinks into the deep ocean.
