Wegener's  idea on continental drift and did not surprise meant that his theory was not  immediately accepted.

It is the gradual movement of the continents across the earth's surface through geological time. So the scientist Wegener was an upcoming meteorologist. He found that in other continents there was the same fossils  in West Africa and south america. He was the one to discover the idea of continental drift, but some geologist didn't accept the idea due to him not having enough evidence to support the theory that

Alfred Wegener used fossil evidence, such as that of tropical plants found on the Arctic island of Spitzbergen. He found large-scale geographic features that matched, like the Appalachian Mountains in the United States and the Scottish Highlands, as well as rock strata in South Africa that matched those in Brazil. He argued against the claim that earlier land bridges between the continents had sunk.

The knew that his ideas, if accurate, would shake the foundations of their discipline. Wegener was not even a geologist.  Who was he to overturn their field? Besides, he couldn't explain what force could be immense enough to cause the continents to plow through the Earth;s crust like an icebreaker cutting through frozen sheets of ice.

He would use the sonar equipment. Ship commanders would turn on sounding to navigate when docking but Hess left his ship gear on all the time to later find out that the bottom if the sea was not as smooth as he expected. The bottom of the sea in fact had  canyons, trenches, and volcanoes. Other researches found that a huge rift ran along the top of the Mid-Atlantic ocean, Hess knew that the earth's crust had been moving away on either side of the ocean ridges. The ridges ran down the Atlantic and Pacific oceans. They were long and volcanically active.

Plate tectonics was one of the main ideas when it came  to the discovery that the seafloor was spreading. There are multiple plates that move the ocean's floor. when they collide the ocean floor. They found out that there was plate tectonics due to harry Hess and other scientist using sonar equipment.
