Answer to Question 1

True

Answer to Question 2

Alfred Wegener is generally credited with developing the hypothesis of continental drift. Wegener proposed that all landmasses are slowly moving across Earth's surface. He portrayed his grand concept of continental movement in a series of maps showing the breakup of a supercontinent he named Pangaea and the movement of the various continents to their present-day locations.

Evidence he gave supporting his claim included continental fit, similarity of rock sequences and mountain ranges, glacial evidence, and fossil evidence.

Many geologists rejected his idea because no one could provide a suitable mechanism to explain how continents could move over Earth's surface.
