Rain caused by trees is explained.
The trees take water from the soil and give off in the environment by the stomata of leaves. The leaves lose water as water vapour in the environment during photosynthesis. It increases moisture in the environment. This happen continuously in the environment. After sometime, leaves are not able to release water in air which leads to precipitation or saturation of water vapour in the air. Therefore, water fall down on the Earth and it is called rain.
