Let's be honest — the first time you saw <h1> and <h2> tags in some tutorial, your eyes probably glazed over. That's fair. Most explanations make headings sound way more complicated than they are. So let's fix that. What is a heading, really? Think about a book. Every chapter has a title in big letters. That title tells you "hey, this is where a new chapter starts, and here's what it's about."

Fulgurites are old news, geologically speaking — they've been recognized since the early 1700s. The basic idea is simple: lightning is absurdly hot, <cite index="3-1">reaching temperatures around 30,000°C</cite>, which is several times hotter than the surface of the sun. When a bolt like that hits sand, soil, or rock, it doesn't just scorch the surface — it melts it, instantly. Because the ground cools f...
