One of the most pleasant smells, the scent of rain falling on dry earth is called petrichor.
The trees and plants give off volatile oils and these are absorbed by the rocks and earth. When it rains, these oils are released again and the gas they produce is called petrichor. The same oils are responsible for the haze that gives the Blue Mountains their name.
