How volcanic ash does affect us after an eruption? This question has been in my head for weeks after I heard about the flight delay because of volcanic ash. Volcanic ash can is harmful to human health, to our livestock and crops, and to the atmosphere.

The ash can affect the atmosphere in many ways. Firstly, it can turn the sky a hazy and pale yellow colour, and after it turn to gray or black. From it being so dark it makes the temperature go down. Loud thunder and lightning as well as the strong smell of sulfur accompany as the ash falls. Volcanic ash can stay in are atmosphere anywhere from a few week to a few years.

This can be dangerous to our health and food supply, because it can cause tons of damage in many ways for us. If fluoride is present in high concentrations, it can produce a fluorine poisoning and death can occur in livestock that gaze on ash-covered grass. The abrasive texture can cause irritation and scratching of the surface of the eyes. Furthermore, the combination of volcanic ash with moisture in the lungs can create a substance akin to liquid cement.

I just covered some of the effects of that volcanic ash has on us. It has helped my understand of what happen in those place where the volcanic ash drifted too, and how it affect those poor people that lived there. Also what happen to the atmosphere too.
