Geology plate techtonics

            
             The article "Plate Tectonics on Mars" written by Ron Cowen, was about how the magnetic map revealed ancient activity on Mars. At first the scientists first anticipated the movement in 1912, but wasn't established until the late 1960's. Plate tectonics are the theory that explains the tectonic behavior of the crust of the Earth in terms of several moving plates that are formed by volcanic activity at oceanic ridges and destroyed along great ocean trenches. .
             As with many scientific advances, the plate tectonic theory was not fully conceptualized until a basis of relevant data had been assembled. Just as in the theory of plate tectonics of the planet earth, the same information is what is stated in the article about Mars. New measurements of Mars" magnetic field suggest that plate tectonics reigned supreme on Mars. The movement of sheets of crust could have been every bit as important in the Mars of long ago as it is on Earth today. Planetary scientists have challenged for more than 25 years that water was once abundant on Mars. Early images had revealed dried up channels scarring the planet's surface. .
             "If one believes early Mars was wet, then it makes plate tectonics more reasonable," says Gerald Schubert of the University of California, Los Angeles. "Alternatively, one could turn this around accept plate tectonics, and use this as independent support for a lot of water on early Mars." The movement of plates pushed up rock from depths o Mars and brought it back down again, therefore could have transported both water and carbon dioxide. Plate tectonics would have added support to the view that Mars was once a warmer, wetter place with a temperature bearable for life. The point of this article could explain the main question: Is the surface of Mars once had an abundant supply of water, where did it all go? .
             Many scientist had their ideas of what occurred on the planet Mars.
