Petrichor: The Enchanting Scent of Rain
A Definition and British Pronunciation
Petrichor: What is it?
Petrichor, pronounced "peh-trih-core," is the distinctive scent that accompanies the first rain after a long period of dry weather. It is an earthy, musty aroma that is often described as pleasant and refreshing.
The Science Behind Petrichor
Petrichor is caused by a combination of organic compounds released by plants and microorganisms in the soil. When rain falls, these compounds are released into the air, giving the rain its characteristic scent.
The main compound responsible for petrichor is geosmin, a terpene produced by a type of bacteria called Streptomyces. Geosmin is also found in some plants, such as beets and carrots.
