One day while scientists were exploring the sea floor, they discovered sea-floor spreading, thus proving Wegener's hypothesis to be correct.
Harry Hammond Hess (1906-1969) developed theories of plate tectonics, particularly seafloor spreading as the source of new oceanic crust.
It helps them determine the frequency of shifts in the magnetic orientation of the Earth, and initially led to the confirmation of seafloor spreading at the mid-ocean ridges.
Almost, but it has some spreading. Laser diodes are monochromatic.
The observation that led Galileo to conclude that the sun rotated was when he looked through his telescope and noticed that their were sunspots on the sun. He later looked through the telescope once again and couldn't see the sunspots.

The observation that led Alfred Wegener to develop the hypothesis of continental drift was that the continents looked like a puzzle that could fit together and then found out that fossils of similar kind and whats left of similar plants were found on opposite sides of the world.
Plate tectonics is the combination of the seafloor spreading and continental drift. When Alfred Wegner described this process it was rejected due to lack of evidence. Since, we have discovered new evidence and proven his theory true.
The primary hypothesis is that they were led to extinction by hunting by humans.
