Under the Earth, rocks can change shape and form through metamorphic processes, just like clay in a kitchen changes when you press it.
Imagine you have a big lump of Play-Doh, that's like a rock deep inside the Earth. Now, if you press it with your hands while it’s warm, it gets squished and reshaped. That’s what happens to rocks during metamorphic processes. Heat and pressure from inside the Earth can make them harder, smoother, or even create shiny layers, just like when you press Play-Doh and get cool new patterns.
How it works
Rocks start as one kind, maybe a sedimentary rock like sandstone, and then go through metamorphic processes, turning into something else, like marble or slate. It’s like taking cookie dough and baking it in the oven, you get a different texture and shape.
Sometimes, these changes happen very slowly over millions of years, just like how your cake rises gradually in the oven. The Earth is like a giant kitchen, and rocks are the ingredients being cooked under heat and pressure!
