2.1: Alfred Wegener’s Continental Drift Hypothesis
Gettysburg College An Introduction to Geology (Johnson, Affolter, Inkenbrandt, and Mosher).
Wegener was convinced that all of Earth’s continents were once part of an enormous, single landmass called Pangaea. Wegener, trained as an astronomer, used biology, botany, and geology describe Pangaea and continental drift. For example, fossils of the ancient reptile mesosaurus are only found in southern Africa and South America.

A Meteorologist, a Geologist, and the Theory of Plate Tectonics. Alfred Wegener produced evidence in 1912 that the continents are in motion, but because he could not explain what forces could move them, geologists rejected his ideas. Almost 50 years later Harry Hess confirmed Wegener’s ideas by using the evidence of seafloor spreading to.

It took more than 50 years for Wegener’s theory to be accepted. One of the reasons was that it was difficult to work out how whole continents could move. It was not until the 1960s that evidence.

4.1: Alfred Wegener and the Theory of Plate Tectonics
Wegener coined the term Pangaea (“all land”) for the supercontinent from which all of the present-day continents diverged. Figure 4.1.2 4.1. 2 Distribution of similar fossils across the continents, suggesting they were once connected into a single supercontinent (Steven Earle, “Physical Geology”). Wegener pursued his theory with.
At the time of publication, it represented the best available science. Alfred Wegener proposed the theory of continental drift – the idea that the Earth’s continents move over hundreds of millions of years of geologic time – long before the idea was commonly accepted.
Continental drift. Continental drift is the hypothesis that the Earth’s continents have moved over geologic time relative to each other, thus appearing to have “drifted” across the ocean bed.  The idea of continental drift has been subsumed into the science of plate tectonics, which studies the movement of the continents as they ride on.

Reading: Wegener and the Continental Drift Hypothesis
Alfred Wegener suggested that continental drift occurred as continents cut through the ocean floor, in the same way as this icebreaker plows through sea ice. Wegener put his idea and his evidence together in his book The Origin of Continents and Oceans, first published in 1915. New editions with additional evidence were published later in the.
