Abyssal plains were not recognized as distinct physiographic features of the sea floor until the late 1940s and, until very recently, none had been studied on a systematic basis. They are poorly preserved in the sedimentary record, because they tend to be consumed by the subduction process.
The first man to discover that the earth moves around the sun was an Italian scientist named Galileo Galilei.
Rather than being a perfect circle, the Earth moves around the Sun in an extended circular or oval pattern. This is what is known as an âellipticalâ orbit. This orbital pattern was first described by Johannes Kepler, a German mathematician and astronomer, in his seminal work Astronomia nova (New Astronomy).
