This photograph was taken in Pompeii volcano. People’s bodies hardened after the volcanic eruption. I wonder how high of a temperature the eruption was to the point where it hardened bodies. Volcanic activity is a phenomenon in which a stone in the earth's mantle melts at a hot temperature and climbs up to a weak part of the earth's surface.The magma is melted in the ground, and it is lava that comes out of the volcanic eruption. And the reason why the volcano is different from each other is different depending on whether there are many gooey stuff from volcanic eruption or not. If there’s a lot of goo, it becomes Jeju’s Sambang mountain or Japan’s Fuji mountain. It basically looks like a tall bell.

I realized that volcanoes are very dangerous to us.
