Good morning all :)
I want to share about Rain .
The rain that fell the ground and trees are always leaves a distinctive odor refreshing .
There are many theories explaining the origin of these smells, one of the compounds released by the soil and rocks are petrichor.
This compound was first revealed by the 2 researches from the Commonwealth Scientific and Industrial Research Organisation (CSIRO), IJ Bear and RG Thomas .
The study was published in a report entitled "Genesis of Petrichor" and published by the journal Nature in 1965 .
Petrichor derived from 2 Greek words, namely Petros which means stone and ichor which means water . In Greek mythology, petrichor a smooth fluid flowing in the veins of the gods .

The researches believe , a compound that has the chemical name 2 decanone was released by the plants in the dry season and then be absorbed by soil and rocks .
By rocks, the compound was released back when the humidity is experiencing such as drastic change before and after the rain falls .
Until now , the theory developed by CSIRO scientists is considered most able to explain a phenomenon peculiar smell that smell before and after the rain .
Many other theories that say the smell of rain is typical of spores . But until now , petrichor is a compound of the most distinctive smell of rain prove it .
I like the distinctive smell that makes the air smell fresh , especially if the early morning .
See ya in my next post :)
