Models are important in science. Some models are verbal models, which are full elaborate descriptions that can help someone visualize the concept. You have seen
various visuals of Earths layers. Create a verbal model of Earths interior. In your
model, describe the following:
1. The main layers of Earths interior and the indirect evidence that helped us
determine the layers.
2. The flow of matter in the mantle and in the core and the effects of that flow.
3. The source of thermal energy and how energy flows throughout the layers.
(Hint: think of the cause of the convection currents)
