(5c)
(i) Agricultural importance: Rain is immensely important to agriculture. Where there is a limitation in water supply the plants do not develop as they should. The water is vital for the maintenance of physiological and chemical processes that takes place within plant structures.

(ii) Source of energy: Rain facilitates electricity supply through hydropower eg Kainji Dam locatedacross the Niger River in Niger State.

(iii) Source of water for drinking: Rain is needed for drinking because it can become as a source of fresh water. Humans require water to survive, as water is needed for us to stay hydrated. Plants and animals are also heavily dependent on it to thrive and survive.
