Mohorovičić discontinuity

Okay kiddo, have you ever eaten a cake? Yes? Good! Imagine the Earth is like a big cake with different layers inside. The Mohorovičić discontinuity, or Moho for short, is like the line where the cake batter changes into frosting.

But instead of cake, the Earth's crust is where we live, and below it is the mantle, which is made of super hot rocks that move around like a liquid. The Moho is the boundary between the Earth's crust and the mantle.

Scientists discovered it a long time ago by studying earthquakes. When an earthquake happens, it sends waves through the Earth, and different types of waves travel at different speeds through different layers. So by measuring how long it takes for waves to travel through the Earth, scientists can figure out where the Moho is.

Why is the Moho important, you ask? Well, it tells us about the structure of the Earth and how it was formed. Plus, the Moho can influence how earthquakes happen and where volcanoes erupt.

So, there you have it! The Mohorovičić discontinuity is like the line where cake batter becomes frosting, except it's the line between the Earth's crust and mantle, and it helps us learn more about our planet.
