What is the term for the process through which plants release water vapor into the atmosphere?

The process through which plants release water vapor into the atmosphere is known as transpiration. This occurs when water absorbed by the roots of plants moves through the plant and is eventually released as vapor from small openings on the leaves called stomata. Transpiration is a critical part of the water cycle, as it not only helps to regulate the temperature of the plant but also contributes to the overall moisture in the atmosphere. In addition to supporting plant health, this process is significant in maintaining local and global weather patterns, as the released water vapor can condense to form clouds and eventually lead to precipitation.

In contrast, condensation refers to the process where water vapor cools and turns back into liquid, while evaporation is the transformation of liquid water into vapor, typically from surfaces like lakes or oceans. Precipitation encompasses all forms of water, such as rain, snow, or hail, that fall from the atmosphere to the ground but does not refer to the water vapor being released from plants.
