Final answer:
Sonar technology provided additional evidence but it was the accumulation of evidence and the development of plate tectonics that convinced scientists to accept the Continental Drift hypothesis.
Step-by-step explanation:
The acceptance of the Continental Drift hypothesis was not mainly influenced by sonar technology. Rather, it was the accumulation of evidence and the development of the plate tectonics theory that convinced scientists to accept it.
Alfred Wegener first proposed the idea in 1915 based on evidence such as the fit of continents, matching fossils, and similar mountain ranges. However, he lacked a mechanism to explain how the continents moved.
It wasn't until the 1960s, with the development of advancements in geology, oceanography, and geophysics, that a clear mechanism, known as plate tectonics, was understood.
Sonar technology, which uses sound waves to map the seafloor, was instrumental in providing additional evidence for continental drift by revealing mid-ocean ridges and subduction zones, which supported the movement of the earth's crust. This, along with other scientific developments, led scientists to accept the Continental Drift hypothesis.
