This period also saw the emergence of a number of societies interested in geographic issues. Then they use logical reasoning and some imagination to develop a testable idea, called a hypothesis, along with explanations to explain the idea. Geography as a discipline (1.2) a) originated in ancient Greek interest in the nature of the universe and the varying character of the known parts of the earth.
