Graphic renditions of cut aways of Earth’s structure showing crust, mantle and core (left) and of the convecting mantle (right). The relevant dimensions are that the Earth’s average radius is
The critical Rayleigh number
Explain how mantle convection contributes to the movement of tectonic plates on Earth’s surface.
According to Figure 1, which layer of Earth is directly responsible for convection currents?
Based on Figure 2, what happens to a thermal perturbation when the Rayleigh number (
Which statement best explains why larger temperature differences between Earth’s core and surface increase tectonic activity?
Describe how scientists can use mantle convection models and Rayleigh number data to predict volcanic or earthquake activity.
A simulation shows that when the Rayleigh number increases from
Explain how convection provides a mechanism for both gradual and sudden geological changes on Earth.
Which Crosscutting Concept is best demonstrated by the interaction between convection currents, mantle heating, and plate movement?
