Question

Why did other scientists discount Wegener's theory of continental drift? Why did Wegener have a hard time convincing other people that his idea was correct?

A. He couldn't explain how it happened, only that it did happen


B . He had a bad reputation in the scientific community


C. He never published his ideas in a report or book


D. He had no evidence

Answer 1

He couldn't explain how it happened, only that it did happen

Explanation: The answer later came from someone else

Answer 2

Option (A)

Step-by-step explanation:

Alfred Wegener was the person who put forwarded the theory of continental drifting. But it was difficult for him to explain this theory. He had evidences regarding the drifting of the continents but he was not able to determine the main mechanism behind this continental motion. This is why he had a hard time convincing other people that his idea was correct.

Later, over a due course of time, the new and widely accepted theory known as the Plate tectonic theory, was able to prove the mechanism behind the drifting of the continents. The main mechanism behind this was the convection current that generates in the mantle, and these currents were formed because of the heat radiated from the interior of the earth.

Hence, the correct answer is option (A).
