What happens to subducted lithospheric slabs? Flashcards
1
Q
Where do driving forces derive from?
A
60% comes from the direct pull from the upper mantle slabs
40% comes from viscous stresses and gravity

Q
What happens to subducted plates that have resided in the mantle for longer?
A
The longer the subducted slabs reside in the mantle the more they will suffer the effects of extreme pressures and temperatures, and thus become weaker
