Which events increased the water content in earth’s atmosphere? check all that apply.

Ok, so it definitly isn't "The sun released a strong burst of water vapor" because the sun doesn't have water. I'm not too sure about this one " Water evaporated and condensed to form oceans" but I would say yes. "Materials collided due to strong gravitational forces." Yes. That's how the earth was made. "The ozone layer formed to protect against harmful UV ray exposure." Yes. It acts as a sort of filter so we all don't disintegrate as soon as we step outside (bit of exaggeration but whatever). "Water vapor increased during formation of the early atmosphere." yes. I do hope this helps
