What is Earth's crust?

Earth’s crust is like the skin on top of our planet, it’s what we walk on and dig into every day.

Imagine you have a big chocolate bar, and you break off just the top layer to eat. That broken-off piece is like Earth's crust, it’s the thin outer part of Earth that we can see and touch. Just like how the chocolate isn’t the whole bar, the crust isn’t the whole Earth.

The crust is made of rocks, which are like big, hard pieces of candy. These rocks come in different types, some are smooth, some are rough, just like different kinds of candies. Underneath these rocks, there’s also soil and sand, which are like the crumbs that fall off the chocolate bar when you eat it.

Sometimes, the crust moves a little bit, like when you push your fingers together on a soft candy, this movement can make mountains or cause earthquakes! Earth’s crust is like the skin on top of our planet, it’s what we walk on and dig into every day.
