Slab pull occurs because subducting slabs are ________.
A)less mafic,and therefore less dense,than surrounding asthenosphere
B)cooler,and therefore more dense,than surrounding asthenosphere
C)hotter,and therefore more dense,than surrounding asthenosphere
D)cooler,and therefore less dense,than surrounding asthenosphere

Question

Quizplus · Accepted Answer

Subducting slabs are cooler than the surrounding asthenosphere, causing them to be more dense. This difference in density causes the slab to sink further into the mantle, pulling the rest of the plate along with it. This process is known as slab pull.
