The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.

<h3>What is the indirect evidence that helped us determine the layers?</h3>

Use of seismic waves is the indirect evidence that helped us determine the layers. When earthquakes occur they produce seismic waves.

The flow of matter occurs by convection. The dense crust subducts back into the mantle exert forces on crustal plates that then move, producing tectonic activity.

So we can conclude that The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.
