Diagenesis

Diagenesis happens when tiny bits of rock get squished and mixed around by the earth's forces over a very long time. Think of it like play-doh that you mash and squish with your hands for a very long time. This can change the rock's shape, color, and even what it's made of!

Diagenesis can happen to a lot of different types of rocks, like sandstone, limestone, and shale. Sometimes, water or other fluids seep into the rock and add new minerals or take some away. This can make the rock stronger, weaker, or even break it apart. Imagine pouring paint on your play-doh and watching it change color!

The earth's pressure and heat also play a big role in diagenesis. Sometimes, the pressure from layers of rock above can make a rock harder or flatter. Other times, heat from the earth's core can change the rock's shape or make it into something completely different! Think of putting your play-doh in the oven and watching it get hard and change shape.

Overall, diagenesis is a really cool process that happens over a very long time and can change what rocks look like, how strong they are, and even what they're made of!
