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.
What did Galileo conclude from his observations of Jupiter and Venus? Galieo discovered that the moon has mountains and that the Sun spins. He also discovered that Venus has phases like the Moon. One of Galileos most important discoveries was thâ¦at Jupiter has four moons that orbit around it.
