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.
How does Earth keep its orbit around the Sun and not come closer to the Sun. Answer 1: The Earth is always being pulled towards the Sun by gravity. If the Earth were stationary compared to the Sun, it would fall into the sun under the force of gravity.However the Earth is actually moving sideways compared to the center of the Sun at 3 km/second (~2 miles/second).ow does Earth keep its orbit around the Sun and not come closer to the Sun.
