Petrichor

Petrichor is the distinctive, earthy scent produced when rain falls on dry soil. This aroma is caused by a combination of volatile organic compounds (VOCs), including geosmin, released by certain soil-dwelling bacteria, and oils secreted by plants during dry periods. The scent is often associated with freshness, rejuvenation, and the end of a dry spell, creating a feeling of nostalgia and connection with nature. The intensity of petrichor can vary depending on the soil composition, the intensity of the rainfall, and the types of vegetation present.
