AS you can see the first layer is the crust, the crust is around 50 km and the ratio of the km to cm is 260km to 1cm using the ratio, we can find out that the crust is approximately 0.19 cm moving on the lithosphere is 140km away from the crust and again, using the ratio we know that the lithosphere is about 0.53cm long.  The mantle is around 2900km away from the crust so using the ratio the mantle is 11.1cm, up next we have the outer core, the outer core is 5100km away from the crust using the ratio, the outer core is 19cm away from the crust. The last layer is called the inner core, it is 6371km away from the crust.
