The Origin of The Distinctive Smell of Rain

The Origin of The Distinctive Smell of Rain - Has it ever crossed your mind from where the smell of an odor was noticeable in typical time it rains???, or usually also appear before the rain came down??

You who do not know, here's the explanation, the Rain wetting down soil and trees always leaving a refreshing bebauan typical.

There are many theories that explain the origins of bebauan, one of the compounds released by the soil and rocks that petrichor.

The compound was first revealed by two researchers from the Commonwealth Scientific and Industrial Research Organisation (CSIRO), IJ Bear and RG Thomas. The study is published in a report entitled "the Genesis of Petrichor" and was published by the journal Nature in 1965.

Quoted from The Naked Science, petrichor comes from two words in the language of Greece, petros meaning rock and the mean water. ichor In the mythology of Greece, petrichor is a liquid that flows in the pulse of the gods. The researchers believe, compounds that have the chemical name 2-this decanone released by plants during the dry season and then absorbed by the soil and rocks.

By the rocks, the compound it is released again when humidity changes drastically for example before and after the rain. Until now, the theory developed by CSIRO scientists is judged most can explain the phenomenon of the odor was noticeable smell typical before and after the rain.

There is also another theory that is to say, the typical smell of rain is caused by spores produced by a bacterium called actinomycetes. These bacteria often live in wetlands, but easy to die when the ground is dry or moisture loss. Before dying, the bacteria were left the eggs in the form of spores that have staying power is much more powerful. In the dry soil conditions, Spore's hibernation so that it can live up to all these years.

When rain soaks the soil, the spore-spore that came to life and some of them escape from the ground and inhaled by humans. The smell of rain is typical it is actually a spore which inhaled by humans.

This theory is corroborated by the results of the experiment, which membutikan that the breeding laboratory actinomycetes spores can produce a smell like rain. However, this theory does not explain the similar odor that sometimes it appears just before the rain came down.
