In your opinion, what factors produced the long delay between the time of Wegener’s lectures and book and the time of acceptance of his theory?
What will be an ideal response?
Scientists at the time, knowing little of Earth’s interior structure and bound by an inertial mindset as to how continents and mountains were formed, were unreceptive of Wegener’s revolutionary proposal and, in a non-scientific spirit, rejected it outright. Aided by an avalanche of discoveries, the theory today is nearly universally accepted as an accurate model of the way Earth’s surface evolves, and virtually all Earth scientists accept the fact that continental masses move about.

Why is the Moment magnitude scale favored over the Richter magnitude scale?
A) The Richter magnitude is based on older models of seismographs that are no longer used to record earthquakes. B) The Richter magnitude always underestimates the amount of energy released by an earthquake. C) The Moment magnitude measures the total energy released by an earthquake. D) The moment magnitude carries the calculated values out to more decimal places so it is more precise.
