Volcanic Lightning

The impressive spew that comes from an erupting volcano has all sorts of things mixed in it, including superheated chunks of rock and gases shooting into the sky. But, along with all that, it’s not rare to see lightning shooting from an ash cloud.

Usually, we see lightning because small bits of ice form in thunderclouds. Thunderclouds always have winds blowing upward and downward, so those particles will crash together and become electrically charged. The same thing happens when you rub your hair on a balloon – both parts in contact get electrified, and that’s why your positively-charged hair sticks to the negatively-charged balloon. Opposite charges attract.

The same thing happens in a more chaotic environment inside a thunderstorm. Some of the ice formations are heavier than others, which mean some lighter particles become positively charged and rise to the top of the storm, and denser, negatively charged ones stay near the bottom. Lightning is a big spark of electricity connecting points with imbalanced charges, whether they’re between two regions of the cloud or the cloud and the ground, and makes them balance out until there’s another build-up.

But in a volcano, there is no ice forming inside ash clouds. Instead, the bits of broken rock are the ones rubbing against each other and creating electricity; because lightning can be 5 times hotter than the sun and volcanoes are so dangerous, it is hard to study the details of this phenomena. However, the heat of the lightning often turns the ash it touches to liquid, which later solidifies into little spheres of glass that can tell us about how long and how hot the strike was.

From the text, we can infer that . . . .

Soal menanyakan kamu apa yang dapat disimpulkan dari teks di atas.

Teks di atas menjelaskan bagaimana fenomena alam 'Volcanic Lightning' atau petir vulkanik terjadi sehingga termasuk ke dalam jenis explanation text.

"But in a volcano, there is no ice forming inside ash clouds. Instead, the bits of broken rock are the ones rubbing against each other and creating electricity; because lightning can be 5 times hotter than the sun and volcanoes are so dangerous, it is hard to study the details of this phenomena."

Berdasarkan kutipan di atas dapat disimpulkan bahwa fenomena alam petir vulkanik sangat unik karena pada umumnya petir terjadi karena es yang terbentuk dari awan. Namun pada fenomena ini gesekan pada pecahan batu yang menghasilkan petir.

Oleh karena itu, peneliti tertarik untuk mempelajarinya namun fenomena ini sangat berbahaya untuk dipelajari.

Jadi, jawaban yang benar adalah  Volcanic lightning is one of the unique and dangerous natural phenomenon to study
