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>

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.

DNA is a negatively-charged molecule. Also cell membranes are negatively charged. The problem would be how to push this charges together?
