What knowledge about the Earth as my planet did the ancient scientists of Europe have?

Scientists of Ancient Greece studied the causes of earthquakes, winds, floods of the Nile, the origin of land and sea, and the distribution of heat on Earth. They were the first to come up with the idea that the Earth is in the shape of a ball. Aristotle in the 4th century BC gave evidence of the sphericity of the Earth and expressed the idea of earthly shells.
