The reason why it is good to enjoy the cool under the big trees is that:
(1) The big tree has a big crown and a big shade
The area of tree crown contacting with air is large, water evaporation is fast, and more water is needed
(2) During the day, the air under the big trees is fresh
During the day, plant photosynthesis is to convert light energy into biomass energy
(3) In hot summer, the air under big trees is wetter and cooler than other places
When the water in the leaves evaporates, it needs to absorb heat from the surroundings, so it is cooler under the trees



Why is it cool under a big tree?
As above, in connection with the transpiration of plants, the explanation of the three state change of water is given


Because the transpiration of plants needs water... Water evaporates from stomata in the process of transpiration, and the evaporation needs to absorb heat, and the liquefied water vapor also needs to absorb heat, so the ambient temperature will drop
