Alfred Wegener's theory?
The weakness in Alfred Wegener's theory on Continental Drift was his reason for what drove the plates to shift was they crashed into each other. The force behind moving the continents was wrong. Plate tectonics accurately explains the reason plate drift is from magna beneath the earths crust.
Why is alfred wegener's contribution still important?
Perhaps Alfred Wegener's greatest contribution to the scientific world was his ability to weave seemingly dissimilar, unrelated facts into a theory, which was remarkably visionary for the time. Wegener was one of the first to realize that an understanding of how the Earth works required input and knowledge from all the earth sciences. ================= I hope this is helpful.
What was a weakness in Alfred Wegener’s theory of continental drift?
Alfred Wegener failed to identify a mechanism to explain his theory. Just as many men before Charles Darwin who proposed the idea of evolution, they lacked an explanation of a mechanism, and thus were not highly supported. Alfred Wegener had more evidence to support his hypothesis than those before him, but he could not prove it through an observable mechanism. He spent his last breaths working on finding the evidence to support his theory, but unfortunately he did not. It wasn't until after his death that our knowledge of plate tectonics allowed us to revive his theory.
Alfred Wegener said that earth’s continents are moving. Which evidence supports this theory?
Alfred Wegener said that earth’s continents are moving. Which evidence supports this theory? revolution of the Earth similarities in human fossils different types of rocks on opposite coasts close geometric correspondence of continental coastlines 6. What can happen when the earth’s plates slide past each other? A volcano forms. The ocean floor spreads. An earthquake occurs. A rift valley forms. 7. How did Wegener explain the fact that ancient horse fossils showed up on different continents? The horses swam between the two continents. The continents were at one time joined together. The fossils were moved by humans. The fossils must be of different species. 8. What makes plates move? radiation from the sun movement of ice sheets cold air currents on earth’s surface heat convection within the earth
Y did most scientist reject wegener's theory for nearly a half century?
He proposed his theory of Continental Drift in 1915 but had no way to scientifically test it, and had no physical evidence of it. He was a meteorologist, scientist and geophysicist. His hypothesis was accepted in 1950, 20 years after he died.
