The crust was formed around 4.5 billion years ago when the Earth was still in its infancy. It's believed that the crust was created from the solidification of magma that rose to the surface from the Earth's interior. This process is still happening today, which is why we have new landforms and islands popping up!
The crust is made up of different types of rocks, including granite, basalt, and sandstone. These rocks are formed through various geological processes, such as weathering and erosion. It's amazing to think about how these rocks have been shaped over millions of years!
