Question

select the correct answer.
what would likely have happened to earth if no icy debris had arrived?
it would still have atmospheric water but no oceans.
it would still have oceans but no atmospheric water.
it would have no oceans or atmospheric water.
it would have released water in volcanic outgassing

Explanation:

Icy debris (like comets) are believed to have delivered a significant amount of water to Earth. Volcanic outgassing contributed some water vapor (which can lead to atmospheric water), but the large - scale formation of oceans is highly dependent on the delivery of water from icy debris. If no icy debris had arrived, the amount of water would be insufficient to form oceans. And without the continuous supply from icy debris, even the water from volcanic outgassing (which is in the form of vapor initially) would not accumulate in large enough quantities to form oceans.

Answer:

It would still have atmospheric water but no oceans.
