What's happening at the very top/center of the image? (LOOK at the red arrows)
Divergent boundary
Convergent boundary
Transform boundary
What are the red arrows?
Divergent boundary
Convergent boundary
Transform boundary
Convection currents
What explains the rise and fall of the convection currents?
As they get closer to the surface they lose heat and begin to sink back down to the mantle
As they get closer to the surface they gain heat and begin to punch through the crust
As they get closer to the surface they lose heat and begin to rise into the atmosphere
As they get closer to the surface they lose heat, they have to return to the core to gain more heat and energy
