Positive feedback mechanism. A process whereby an initial change in an atmospheric process will tend to either reinforce the process (positive feedback) or weaken the process (negative feedback). See Feedback mechanism.
Transpiration Process. Similar to the sweat glands on your skin, plants have openings on their leaves that allow water to escape, called stomata (singular: stoma). Stomata are usually found on the underside of a leaf to reduce excess water loss, and they're surrounded by guard cells that open and close the pores. Though stomata release water, their main purpose is to exchange gases.
