Which process doesn't have a major effect in shaping planetary surfaces? a. impact cratering b. volcanism c. tectonics d. erosion e. magnetism

e. magnetism

Explanation:

In shaping the planetary surface, the following factor plays a major role, -

impact cratering tectonics volcanism erosion

Magnetism does not play any role in shaping the planetary surface, since it is not a surface phenomena, it the property by which the planet attain its magnetism.

But, the process like, impact cratering, volcanism, erosion, tectonics are all surface phenomena,

and hence

can cause changes on the surface of the planet.
