What are structural shifts?

A structural shift is when something changes its shape or how it works from inside out, like when a building gets taller or turns into a different kind of building.

Imagine you have a toy block tower. It’s strong and stands tall, right? Now imagine that one day, instead of just stacking blocks on top of each other, you start using bigger blocks at the bottom and smaller ones on top. That’s like a structural shift, it changes how the tower is built, which might make it taller or more wobbly.

Think about your favorite playground. It has swings, slides, and maybe a sandbox. One day, they remove the slide and put in a climbing wall. That’s a structural shift, the playground still exists, but its parts have changed, so you play differently now.

A structural shift can also be like when your house gets a new roof or grows an extra floor. It's not just adding something on top, it changes how the whole thing stands up and works together.

Sometimes these shifts happen slowly, like watching a tree grow taller over years. Other times, they’re sudden, like when you drop a big block from the top of your tower, crash! The whole structure changes in an instant.
