Question

which of the following was a limitation for wegener in proving his continental drift theory at his time? question 17 insufficient computing power no evidence of oceanic crust formation limited knowledge of mantle processes lack of fossil records

Explanation:

Wegener proposed the continental drift theory. At his time, the understanding of mantle processes (which drive plate movements related to continental drift) was limited. Computing power wasn't a key factor for his theory's proof. There was evidence of fossil records (matching across continents) which he used. Oceanic crust formation evidence (like seafloor spreading) came later but wasn't the main limitation for him compared to mantle process knowledge.

Answer:

Limited knowledge of mantle processes
