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.
The planet Uranus was discovered by William Herschel on March 13, 1781. He discoverd Uranus while surveying stars in the night sky using a telescope that he had built himself.Herschel noticed that one of these stars seemed different, and after observing it many more times, noticed that it orbited the Sun.He calculated that Uranus had an orbit that was about 18 times farther from the Sun than Earth. Herschel also discovered two of the moons of Uranus (Titania and Oberon).erschel noticed that one of these stars seemed different, and after observing it many more times, noticed that it orbited the Sun.
