SOLAR SYSTEM

Detailed explanation-1: -Magma generation, igneous intrusions, metamorphism, volcanic action, earthquakes, faulting, and folding are usually the result of plate tectonic activity.

Detailed explanation-2: -The correct answer is : Paleomagnetism. Paleomagnetism was not used by Wegener to bolster his theory of continental drift.

Detailed explanation-3: -There is also much climate evidence supporting continental drift, most notable of which is glacial activity. Alfred Wegener investigated this field and found an anomaly in the Permo-Carboniferous ice sheet that was found through glacial till deposits to have once covered all the southern major plates.

Detailed explanation-4: -The processes of seafloor spreading, rift valley formation, and subduction (where heavier tectonic plates sink beneath lighter ones) were not well-established until the 1960s. These processes were the main geologic forces behind what Wegener recognized as continental drift.
