Holmes proposed a theory of continental drift that closely resembles modern interpretations, presenting ideas that were revolutionary for his time. His views faced significant criticism, especially in the United States, where the acceptance of gradual drift took longer to gain traction compared to other regions. Some critics expressed concern that his persuasive presentation could lead students to accept his theories as truths.

This resistance highlights the contentious nature of scientific progress and underscores how radical new ideas often meet skepticism. Despite the pushback, Holmes' arguments laid the groundwork for future acceptance of continental drift, illustrating the struggle between established beliefs and emerging scientific thought in geology.
