Question

vWhich of the following is true about convection in Earth's mantle and tectonic plate motion?
A.
Plate motion and mantle convection are related processes, but they cannot occur at the same time.
B.
Plate motion and mantle convection do not relate to each other in any way.
C.
Evidence suggests that plate motion and mantle convection are related processes.
D.
Evidence suggests that mantle convection stops plate motion from occurring.

Answer 1

C. Evidence suggests that plate motion and mantle convection are related processes.

Brief reason: mantle convection creates forces (e.g., slab pull, ridge push, upwellings/plumes) that drive plate motions, and observations like seismic tomography, subducted slab geometry, ocean-floor ages, heat flow, and hot spots support this connection.
