I looked it up
The continental crust is made up of rocks that consist primarily of silica and alumina called the "sial". The next layer of the Earth is called the mantle.
You see how much the scale is, let's say that it is 150 mm=300 miles. If it goes over, you can measure it with a ruler, or move with your hands, measuring it as well as possible and estimating. Hope this helps! :)
