Why in 1920 did other scientists thought wegener a hypothesis was wrong?

In 1920, many scientists rejected Alfred Wegener's theory of continental drift primarily due to a lack of a mechanism explaining how continents could move. They found his ideas on the continents breaking through oceanic crust implausible and were skeptical of the evidence he presented, which included geological and fossil correlations across continents. Additionally, the prevailing scientific consensus favored the static model of the Earth’s crust, influenced by the then-accepted theories of geology and physics. This resistance to change in established thought contributed to the dismissal of Wegener's hypothesis during that time.
