Method for demonstrating earth physiognomy, revolution and rotation changing process before and after extermination of dinosaurs

Abstract

The invention discloses a method for demonstrating an earth physiognomy, revolution and rotation changing process before and after the extermination of dinosaurs. A pedestal, a bracket, a rail, a rotation shaft, a gear set, a rack, a micro motor, antiskid buckles, raised heads, an earth model, shaft holes at the two ends of a current earth rotation shaft, shaft holes at the two ends of a shaft crossed with the current earth rotation shaft by 82 degrees, a rail trench and the like are mechanically connected, and electrode contacts, a luminous light source, a sound production circuit, a wire, a power supply and the like are electrically connected to form a mechanical earth demonstration model. Cretaceous earth physiognomy and rotation conditions in dinosaur ages, the earth physiognomy, revolution and rotation changing process in the extermination of the dinosaurs, and the earth physiognomy and the rotation conditions after the extermination of the dinosaurs are directly and vividly demonstrated directly in a mechanical and electric or manual way or in a way of making a film or a video film for a demonstration process or making a computer animated film for the demonstration process by using a computer language according to conditions. The method is favorable for people to cognize the fact that a disaster destroys the biosphere and deeply influences the earth and to cognize the objective reality and laws of the earth, the stratum and the geology.

Description

Technical field [0001] The present invention relates to a method for demonstrating the landform and rotation of the earth in the age of dinosaurs, and in particular to demonstrate the whole process of landform change, earth pole movement, revolution wobbling, and rotation repeatedly changing directions due to meteor strikes in space at the end of the dinosaurs. Methods. technical background [0002] The known revolution of the earth in space—the compound motion model of rotation and the revolution and rotation of the earth demonstrated by the rotating globe are all the revolution and rotation of the earth around a fixed revolution orbit and a fixed rotation axis. The fixed rotation The axis takes the north end (upper end) where the meridians converge at zero degrees north latitude, and the south end (lower end) where the meridians converge at zero degrees south latitude. This model is only suitable for demonstrating the earth's rotation movement since the extinction of the ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defect that the existing earth, rotation compound motion model and rotation globe cannot demonstrate the earth's landform and rotation scene in the age of dinosaur life, the invention provides a kind of globe, which can not only demonstrate the earth's landform in the Cretaceous period of dinosaur life, It can also demonstrate the whole process of the earth being hit by meteorites, the extinction of dinosaurs, the movement of the earth's poles, the change of landforms, the revolution drift and the repeated rotation redirection, the rotation axis finally deflected by about 82 degrees, and the appearance of the earth after Today's landform, rotation and revolution
