Detailed explanation-1: -The air caused by the moving of plants and trees helps in the chemical reaction with clouds that are full water loaded thereby bringing rain to the earth. Thus plants play an important role in getting more rain.

Detailed explanation-2: -1. spraying water into warm clouds; 2. dropping dry ice into cold clouds (where the dry ice freezes some water into ice crystals that act as natural nuclei for snow); and.

Detailed explanation-3: -Additionally, environmental protections and broader ecological restoration can accompany reforestation to help in the fight against climate change and provide many other benefits, such as improved water quality.

Detailed explanation-4: -For example, more than 2 square kilometers of forest expansion can increase the possibility of rainfall. Trees transport water to the air, and water vapour moves to another place which can be geographically far from the afforested location, such as to another country or even continent through wind-driven circulation.

Detailed explanation-5: -The roots of trees hold the soil tightly, when trees are removed from the soil, the soil becomes loose and thus soil erosion and floods increase to manifolds. Thus, deforestation has a major effect on the environment and the water cycle which leads to a decrease in rainfall.
