Chapter 27, Problem 3RAT

To determine

The correct option for the statement “Seafloor spreading provided a driving force for continental drift because”.

Answer to Problem 3RAT

The correct option for the statement “Seafloor spreading provided a driving force for continental drift because” is option (b).

Explanation of Solution

The seafloor spreading is the movement of the seafloor due to the relative movements of the plates. The oceanic plates move on each other at the rift.

The continental drift is the movement of the continents due to plates. It occurs due to the driving force that generates due to the pushing of the continents by the seafloor spreading.

The subduction induces the generation of magma and formation of volcanoes on the seafloor. It is closely related to mantle convection.

Conclusion:

Therefore, the correct option for the statement “Seafloor spreading provided a driving force for continental drift because” is option (b).
