Why didn't scientists believe Alfred Wegner?

Scientists initially dismissed Alfred Wegener's theory of continental drift due to a lack of a plausible mechanism explaining how continents could move. At the time, the prevailing view was that the Earth's crust was static, and Wegener's ideas challenged established geological concepts. Additionally, Wegener's background as a meteorologist rather than a geologist led some to question his expertise in the field. It wasn't until the mid-20th century, with the development of plate tectonics, that his ideas gained widespread acceptance.
