Answer 2

Answer:We all know that there is no smell in the raindrops, but when they fall on the earth and mix with the dust, then a kind of aroma or earthy smell appears. This fragrance is called 'petrichor'.

There are three main reasons behind the earthy smell of the soil:

The first reason is the fresh smell that comes after a thunderstorm is due to ozone. According to the scientists ozone has a pungent and a very sharp smell similar to that of Chlorine gas. After rain, some amount of ozone gas present in the atmosphere dissolves with the rainwater due to which the smell or aroma arises.

The second reason is the existence of bacteria. According to scientists, a different type of bacteria is found in the soil, which also causes the smell.

The third reason is the oil secreted by various plants. These oils collect in the environment and when it rains, certain chemicals that make up the oil get released into the atmosphere causing a familiar scent or smell. Also, some scientist says that rain, water, and soil perform some type of reaction, due to which strange fragrance or aroma occurs.
