in my thought I think this is my answer in explanation
Explanation:
Geography was first systematically studied by the ancient Greeks, who also developed a philosophy of geography; Thales of Miletus, Herodotus, Eratosthenes, Aristotle, Strabo, and Ptolemy made major contributions to geography. The Roman contribution to geography was in the exploration and mapping of previously unknown lands. Greek geographic learning was maintained and enhanced by the Arabs during the Middle Ages. Arab geographers, among whom Idrisi, Ibn Battutah, and Ibn Khaldun are prominent, traveled extensively for the purpose of increasing their knowledge of the world. The journeys of Marco Polo in the latter part of the Middle Ages began the revival of geographic interest outside the Muslim world.
