What is the theory that plates have moved apart over tmie?

Alfred Wegeners 1912 theory of Plate tectonics and continental drift.


What was the main counterargument against wegeners evidence?

Many scientists dismissed the theory because it flew in the face of conventional wisdom.


What was the fatal weakness in wegeners theory?

One of the fatal weaknesses in Wegener's theory of continental drift was the lack of a plausible mechanism to explain how continents could move through the solid rock of Earth's mantle. Additionally, Wegener was unable to adequately explain what forces could be responsible for moving the continents.


How did Alfred Wegeners theory support the theory of seafloor spreading?

Alfred Wegener's theory of continental drift suggested that continents move over time on Earth's surface. This theory provided support for the concept of seafloor spreading, which explains how new oceanic crust forms at mid-ocean ridges and spreads outward. Both theories contributed to the development of the theory of plate tectonics, which explains the large-scale movements of Earth's lithosphere.


What were Alfred wegeners accomplishments of his life?

Alfred Wegener is best known for developing the theory of continental drift, proposing that the continents were once joined together in a single supercontinent called Pangaea. He also made contributions to meteorology and polar research, and participated in several expeditions to Greenland. Wegener's work laid the foundation for the modern theory of plate tectonics.
