Abstract

Abstract:

The earth contraction motion is one of crust structure motions that people recognized first. To the parameters related to the earth contraction: perimeter variable quantity (ΔL), ra-dius variable quantity (ΔR), volume variable quantity (ΔV)etc. Theoretical equations are formulated and relative parameter evaluation explained. The process for contraction is divided into 4 stages: volume-shrinking initial stage, perimeter and surface area diminishment stage, contraction force enlargement stage, contraction force diminishment stage. The assembling and collision of plates during the earth contraction process are divided theoretically. There are six types of compression effects between plates divides 6 sorts, that is raising mode, descending mode, covering mode, inlaying mode, push-overlaying mode, rivet groove mode and so on.

Key words: earth, contraction, variable quantity, stage, algorithm, pattern
