Answer to Question 1

Answer: Scientists initially held onto the belief that the continents and ocean basins were fixed objects, both of which dated back to the earliest days of the Earth. When continental drift was proposed, which challenged this belief, scientists had difficulty accepting it because the evidence was not as clear outside the southern continents. After World War II, modern tools like sonar, ocean drilling, and magnetometers were used to gather evidence about the age and bathymetry of the seafloor. This evidence (seafloor spreading and paleomagnetism) was used to support continental drift and develop the modern theory of plate tectonics.
