TERRESTRIAL GLOBE CAPABLE OF CLARIFYING MECHANISM FOR SEASON CHANGES

摘要

PROBLEM TO BE SOLVED: To provide a terrestrial globe which has a function to reproduce earth revolution around the sun added to a function to reproduce earth rotation and is capable of making a comprehensive clarification of astronomical phenomena by associating some phenomena caused by the earth revolution around the sun such as changes in solar altitude or changes in length of day and night with other phenomena caused by the earth rotation such as culmination, sunrise, sunset.;SOLUTION: There is provided a terrestrial globe 8 which has a function to reproduce earth revolution around the sun added to a function to reproduce earth rotation with its outer periphery marked by an earth revolution orbit 10 so that a comprehensive clarification of astronomical phenomena can be made by associating some phenomena caused by the earth revolution around the sun such as changes in solar altitude, changes in length of day and night with other phenomena caused by the earth rotation such as culmination, sunrise, sunset.;COPYRIGHT: (C)2014,JPO&INPIT
