(a)  

What formed in a divergent boundary when it is a continent?

(a)

(a)  

Part of the driving force for plate tectonics, this process moves heat from the interior of the Earth towards the surface, as cooler plates sink back into the mantle.

(a)  

Plate boundary where the plates move apart

(a)  

 This type of crust is thicker than oceanic

and doesn’t subduct

(a)
