When does water vapor form in the atmosphere?

Water vapor forms in the atmosphere under certain conditions. For water vapor to form, water must be heated to its boiling point of 100°C (212°F) at sea level atmospheric pressure. When liquid water is heated to this temperature, it transitions to a gas state known as water vapor.

Some key ways that water vapor forms in the atmosphere include:

- Evaporation of water from oceans, lakes, rivers and other bodies of water. As the sun's energy warms these surfaces, it provides enough heat energy to transition some of the liquid water into a gaseous state.

- Transpiration from plants. Plants absorb water from the soil through their roots and "breathe out" water vapor through pores in their leaves called stomata.

- Sublimation of ice or snow when air temperatures rise above freezing. The solid ice transitions directly to water vapor without first becoming a liquid.

- Condensation of water vapor that is already in the air when air rises and cools. As moist air rises, it expands and cools. When the air reaches its dew point temperature, water vapor condenses out as liquid water droplets.

So in summary, for water vapor to form the key requirement is sufficient heat energy to transition liquid water into its gaseous vapor state, which most commonly occurs through evaporation from large water surfaces or transpiration from plants. The sun provides most of this heating energy through its radiation.
