From the oceans
evaporate
Nerve agents are highly toxic in all forms whether solid, liquid, or vapor
Ice, liquid, and vapor
it measures the water vapor content of air or the humidity.
In concentrated amounts yes but it is recommended to avoid it's vapor and seek fresh air.

is water vapor
Scientists studying the Earth's climate changes have found that increased temperatures lead to increases in water vapor in the atmosphere, which adds to global warming. This means that increases in temperature and water vapor feed each other.
Clouds, fog.
I think you can figure this one out.
There is no first in a cycle but, most are comfortable thinking ice melts to water, water evaporates to vapor, vapor condenses and fall to earth as rain to snow.
Primarily hydrogen, with probably water vapor, methane and ammonia.
H
It condensed water vapor to form the oceans by the Earth's vapor into the water.
Condensed water vapor from the sky typically falls back to Earth as rain.
The water vapor concentration constantly fluctuates.
The stratosphere contains almost no water vapor.
