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 Earth's layers. Create a verbal model of Earth's interior. In your model, describe the following: (6 points)
The main layers of Earth's interior and the indirect evidence that helped us determine the layers.
The flow of matter in the mantle and in the core and the effects of that flow.
The source of thermal energy and how energy flows throughout the layers. (Hint: think of the cause of the convection currents)

Answer:
The main layers of Earth's interior and the indirect evidence that helped us determine the layers.
The flow of matter in the mantle and in the core and the effects of that flow.
Explanation:
Answer:
The main layers of the Earth's interior are the Crust, Mantle, and Core. The Crust is the outermost layer of Earth.
The Mantel is the middle layer. And there are two parts to the Core; The outer core is thought to be molten and the inner core is solid Iron. Experimental techniques and advances in scientific knowledge allow scientists to study Earth's interior.
Because of the plasticity of the mantle, there is a flow of matter even when it is solid.
When particles heat up they rise, but when they cool down they fall. So, the heat in the earth creates a convection current in the mantle that flows from the core to the crust. As the current rises to the crust, it cools down causing it to fall back down to the inner earth where the temperature increases again and the process repeats.
