I Love the Smell of the Earth After the Rain

How amazing it is! The moment when the rain drops hit the ground, a fresh earthy fragrance rises.
What is it made of? Science would give all the answers, but i'd rather imagine it on my own.
That amazing fragrance might be coz of the raindrops leaving their form, their shape of drop and embracing the earth, getting dissolved into the earth, giving up themselves to serve and quench the thirst of the dry earth. They dissolve themselves and the fragrance rises.
How sweet! ^^
