Do you know the Earth would look like after 200 million years? According to geologists forecast, the Mediterranean and the Red Sea will disappear, Los Angeles will go to Alaska, the Indian Ocean will become an inland sea, Asia, Africa and the Americas and other continents will be linked together to form a new "super-continent."
Forecast Earth dynamics of the various continents of origin in the 196 0 era "of plate tectonics theory", in the past, scholars thought that the mainland is not fixed, but the idea of plate tectonics theory, the earth's crust by the seven major plates and several smaller plates composed of twenty, These plates are located on top of the magma, as thermal convection and gravity and slow-moving.
Continental drift of the continents will be linked together
China Mobile has given rise to two roles: rifting and subduction, the role of rifting occurred in the two plates away from each other from upwelling of magma at the bottom of the formation of new crust; role subduction occurred in the two plates bump into each other's edge, which into a plate to another plate, and then in the gradual elimination of the letter.
In plate tectonics theory was widely accepted and followed, many geologists to use this theoretical study the face of the Earth's past, and put forward the "Pangea" (Pangea) advocates that the Earth is only one in the former 200 million years"super continent", followed by geological scholars Diaz (Robert Dietz) go further and begin to predict the future face of the Earth to study, he issued during the 197 0 paper predicted that Southern California, constantly moving north, Los Angeles and San Francisco will become 10 billion years neighbors , Alaska sea 50 billion years face.
This paper made at the University of Chicago study Cervantes Institute of Historical Research (Christoph er Scotese) a great deal of interest from in-depth study in this area, he used computer graphics program outlines the evolution of the Earth's past and tries to depict the face of the Earth's future . In 1982, History of Cervantes to accept the "discovery" (Discover) magazine conferred upon him by the great challenges: the forecast 200 million years look after the Earth.
The unprecedented challenges, have not been enough. History Cervantes said, forecasting the dynamic continents is easier to change their quality perhaps, but rarely completely disappeared, because of its foundation density compared to light a lot of oceanic crust, and then floating above the most difficult to forecast the subduction zone (subduction zone, referring to the Earth's lithosphere convective flow of the settlement area, exists in the ocean plate and continental plates intersect the edge of the polymer plates) development.
According to History of Cervantes forecast the future of the Earth's continents will once again linked to form a what he called the "ultimate Pangea" (Pangea Ultima) new super-continent, first of all, the Mediterranean will be gradually closed, and then in 2500 millions of years to between 75 billion years, Australia will be moving north, one after another with Indonesia, Malaysia and the Philippines convergence, and ultimately merged with the Asian continent.
The new super-continent the Indian Ocean inland sea change
Antarctica also will drift north, the gradual disappearance of its ice cap, about 100 million years , the Antarctica to enter the Indian Ocean, and then separated after 50 billion years, Antarctica will be embedded into the island of Madagascar and Indonesia is the middle, when the Indian Ocean will become land-locked sea.
History Cervantes said that, in the same time the biggest plate change will occur in the Atlantic, a huge undersea subduction zone in the formation and gradually eat up the Atlantic sea-bed, and slowly closed the Atlantic Ocean to the 200 million years, this closure the role of Newfoundland will hit Africa, Brazil hit South Africa, then this process will be accelerated, 250 billion years, the Earth will be linked continents stretch.
History of Cervantes him this study named "Study of the ancient map plan," he established in 1998 www.scotese.com. Websites, and netizens to share his research experiences so far point of access to more than 3 million have been tens of millions. In recent years, al Global Positioning System and the small base station popularity thanks to changes in the earth's crust and scholars study the information more precise, also led to the rapid development of this field.
