  • Continental Drift: Exploring Alfred Wegener's Evidence & Challenges
    You're asking for a trick question! Alfred Wegener never presented any evidence for continental drift. He proposed the theory in 1912, but it was not widely accepted until the 1960s when more evidence was discovered.

    Here's why:

    * Wegener lacked a plausible mechanism. He couldn't explain how continents could move through the Earth's crust.

    * His evidence was circumstantial. He noted similarities in fossils, rock formations, and climate patterns on different continents, but these could have been explained by other theories.

    The evidence that eventually supported continental drift was gathered after Wegener's death:

    * Seafloor spreading: Discovered in the 1960s, this theory explained how the continents could move apart due to the creation of new oceanic crust at mid-ocean ridges.

    * Paleomagnetism: The study of Earth's magnetic field in the past showed that continents had moved over time.

    * GPS data: Modern technology allows us to track the movement of continents in real time.

    So, there is no "evidence" from Wegener that you can choose from, as he didn't provide any that was convincing enough to the scientific community at the time.
