Answer:
The earthy scent produced when rain falls on dry soil is technically called petrichor. The term “petrichor” was coined by Australian scientists who were researching the nature of argillaceous odor in 1964. They investigated the aroma coming from moist clay, sediment and rock. The petrichor scent is generally caused due to the secretion of oils by some plants, the generation of geosmin by Actinomycetes bacteria, the presence of ozone, and also our higher nasal sensitivity to the scent of petrichor.
