First, forget everything boring from science class. Igneous rocks start as liquid rock. That’s right—molten goo called magma (underground) or lava (above ground). It’s basically Earth’s lava-lamp interior.
But what’s in that hot goo? Eight main elements make up 98% of it. Oxygen and silicon are the big bosses. They form the backbone of every mineral crystal you’ll meet.
Don’t panic. You don’t need a chemistry degree. Just remember this: silica (silicon + oxygen) is the main ingredient. It decides if your rock is thick like honey or runny like water.
