How Does a Diamond Form Deep Underground?

A diamond is like a special kind of crystal that grows deep inside the Earth, just like how ice cubes grow in the freezer.

Imagine you're stacking blocks really high, each block adds more weight on top. Deep underground, pressure works like stacking blocks: it pushes rocks together very tightly. This pressure is so strong, it's like being squeezed inside a giant hug from all sides!

Now imagine you're cooking an egg in a pan. The heat makes the egg change shape and texture, that’s what happens to carbon deep underground. The carbon comes from old plants or animals that were buried long ago, like the bottom of a giant soup pot.

The pressure and heat together act like a super-powered oven. Over millions of years, the carbon slowly turns into a diamond, hard and shiny, just like how sugar can turn into glass when it’s heated up!
