Air in the forest is generally cooler and has more moisture than air in open area . why ?
Answers
Answer:
The plants and trees present in a forest continually lose water by the process of transpiration. This water is added to the surrounding air and it increases the moisture content of the air and makes it much cooler as compared to an open area.
Answer:
plants use water to transport nutrients up from the soil. In order to do this they have to bring water from the soil up through the roots and stem/trunk then out to the leaves, where the water is then lost to the air as vapor. This is called transpiration. So while canopy trees are mostly transporting at the top, it can increase the humidity around the area. Plants within the forest transpire beneath the canopy and most of the moisture stays there before slowly diffusing outward.
The mechanism that plants use to transport water upward is very similar to how a straw works. The plants have small tubes that are filled with the water mixture that are narrow enough to prevent the water from falling down due to water's natural cohesive and adhesive properties. Different species have different tmwidths of these tubes, and conditions of drought or extreme heat can cause air bubbles (cavitation) to form, which blocks the tube and is bad for the plant.
