Why did Wegener think that continental drift could be used to explain rock scarring in South America, India, and Australia?

Explanation: Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.

The theory of continental drift

Wegener thought all the continents were once joined together in an "Urkontinent" before breaking up and drifting to their current positions. But geologists soundly denounced Wegener's theory of continental drift after he published the details in a 1915 book called "The Origin of Continents and Oceans." Part of the opposition was because Wegener didn't have a good model to explain how the continents moved apart.

He believed that continental drift would explain the rock scarring because they would have been created when these places approached the glaciers at the poles.

We can arrive at this answer because:

Continental drift is a theory that states that the continents were able to approach and move away, through the movement of tectonic plates.
Through this, Wegener claims that the approximation between Asia, South America, Oceania, and the Earth's poles, may have caused rock scarring of India, Australia, and South American countries.
That's because he claims, it was the glaciers at the Earth's poles that caused these scars.

Although this is a theory, it is a way of explaining the existence of these rock scarring, which may encourage more research to be done to prove or disprove it.
