What is the relation between Wegener's theory and Convectional Current Theory?

Correct answer: Convectional Current Theory helped explain a possible cause of movement

The direct answer is A. Wegener’s continental drift theory said that continents had once been joined and later moved apart, but his original explanation did not clearly identify a satisfactory driving force. Convectional Current Theory proposed that heat inside Earth could create slow circulation in the mantle: hot material rises, cool material sinks, and the movement may help move lithospheric plates. Therefore, it helped explain a possible cause of continental movement, even though modern plate tectonics provides a fuller explanation. Option A is correct. Option B is wrong because the theories are historically related through the question of movement. Option C is wrong because convection is a geological process, not a theory only about farming. Option D is wrong because Wegener did not reject the ocean floor; later ocean-floor evidence helped support continental movement. Exam cue: Wegener described movement; convection suggested a driving mechanism.
