What are transform boundaries?

Transform boundaries are places where pieces of Earth’s crust slide past each other, like puzzle pieces moving around.

Imagine you have a big floor made up of tiles, each tile is like a piece of Earth’s crust. Now, picture some of those tiles sliding slowly next to each other, not going up or down, just side by side. That’s what happens at transform boundaries.

Like a Train on Tracks

Think of train tracks that go straight, when the trains move, the tracks don’t lift or drop; they just slide alongside each other. Similarly, at transform boundaries, parts of Earth's crust move past one another in a long, straight line. This sliding can cause earthquakes, like when you push your fingers together and suddenly feel a little snap.

A Real-Life Example

The San Andreas Fault is a famous example of a transform boundary. It runs through California, and sometimes you can feel the ground shake because the two pieces of Earth’s crust are sliding past each other, just like puzzle pieces moving slowly over time.
