Wegener's theory of continental drift
According to the theory, two major landmasses were formed from the drifting process.
A single landmass called Laurasia, consisting of present day North America, Europe and Asia, was located in the north.
To the south, there was the other landmass, which was called Gondwanaland.
Continental Drift: Theory & Definition - Live Science
Theory states that the Pacific ocean was on the western coast of this supercontinent, while the Tethys ocean was on the Eastern coast.
The drifting process might have started around this time.
Alfred Wegener's theory of continental drift
The German meteorologist Alfred Wegener (1880-1930) is largely credited with establishing the fundamentals of the theory that we now call plate tectonics. The idea that continents may have originally occupied different positions was not a new one (), but Wegener was the first to present the evidence in a diligent and scientific manner.
What was Wegener's evidence for continental drift
The remarkable notion that the continents have been constantly broken apart and reassembled throughout Earth's history is now widely accepted. The greatest revolution in 20th century understanding of how our planet works, known as plate tectonics, happened in the 1960s, and has been so profound that it can be likened to the huge advances in physics that followed Einstein's theory of relativity. According to the theory of plate tectonics, the Earth's surface is divided into rigid plates of continental and oceanic lithosphere that, through time, move relative to each other, and which increase or decrease in area. The growth, destruction and movement of these lithospheric plates are the major topics of this course, but it is first worth considering how the theory actually developed from its beginnings as an earlier idea of 'continental drift'.
