•Your challenge: Provide a claim, evidence, and rationale as to how the continents may have fit together into a super continent approximately 250 Mya. Think like Wegener in 1912!!
700 million years of continental drift in just over 3 minutes!
The earth, is not a solid rock. The top layer of the Earth's surface is called the crust sits, or more appropriately floats on top of a thick and dense ocean of melted rock. The crust is made up plates.
The plates are distinguishable by that are the weak points, or cracks called fault lines.
With the help of convection currents, volcanic eruptions, earthquake and moving water, the plates gradually shift by the pushing and pulling of convection and conduction.
There are 7 plates (While they are very similar to the 7 continents they are not the same)
Eurasian Plate (Asia, Russia and Europe)
African Plate (Africa)
Indo-Australian Plate (Australia and India)
N. American Plate (U.S Canada, Iceland, Mexico)
S. American Plate (South America)
The Pacific Plate (The Hawaiian Islands and Indonesia)
Antarctic Plate (The south Pole. )
•Although Alfred Wegener was not the first to suggest that continents have moved about the Earth, his presentation of carefully compiled evidence for continental drift inspired decades of scientific debate. • •Wegener's evidence, in concert with compelling evidence provided by post World War II technology, eventually led to universal acceptance of the theory of continental drift in the scientific community and eventually the theory of plate tectonics. • •Although others had recognized the fit of Africa and South America, it was Wegener who gathered other scientific data to support his theory.
