Why was wegeners theory rejected

There is also much climate evidence supporting continental drift, most notable of which is glacial activity. Alfred Wegener investigated this field and found an anomaly in the Permo-Carboniferous ice sheet that was found through glacial till deposits to have once covered all the southern major plates. Who discovered plate tectonics? Alfred Wegener. What is the concept of continental drift? Scientific definitions for continental drift continental drift. A theory stating that the Earth's continents have been joined together and have moved away from each other at different times in the Earth's history.

The theory was first proposed by Alfred Wegener in What supports Wegener's theory of plate tectonics? The mobilists were in the opposite camp and supported Wegener's ideas, since many of them had seen evidence for continental motion, especially in the Alps.

Since the north pole is essentially fixed, except during periods of magnetic reversals, this piece of evidence strongly supports the idea of plate tectonics. What are the two tectonic plates called? The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents.

He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true. What evidence proves continental drift?

Evidence for continental drift Wegener knew that fossil plants and animals such as mesosaurs, a freshwater reptile found only South America and Africa during the Permian period, could be found on many continents. He also matched up rocks on either side of the Atlantic Ocean like puzzle pieces. How does glacial evidence support the theory of continental drift? There is also much climate evidence supporting continental drift, most notable of which is glacial activity.

Alfred Wegener investigated this field and found an anomaly in the Permo-Carboniferous ice sheet that was found through glacial till deposits to have once covered all the southern major plates. Who discovered plate tectonics? Alfred Wegener. What is the concept of continental drift? Scientific definitions for continental drift continental drift. His book, "The Origin of Continents and Oceans," was published in Other scientists at the time had observed the similarities in fossils in South America and Africa.

However, many embraced the idea that these were the result of a land bridge between the two continents. In addition, Wegener's explanation for continental drift was weak.

Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere. The plates are around km 62 mi thick and consist of two principal types of material: oceanic crust also called sima from silicon and magnesium and continental crust sial from silicon and aluminium.
