지구의 대륙형성을 15~16세기 베이컨은 대서양 양쪽 해안선 윤곽이 비슷하다는 점을 들어 하나의 대륙이 천재지변에 의해 변형된 것이라고 주장했다. 19세기 들어 허튼은 지구수축설을 들고 나왔고 20세기 초 대륙이동에 대한 논문이 미국의 테일러와 독일의 베개너에 의하여 발표되었다. 특히 베게너는 "대륙과 해양의 기원"이라는 저서를 통해 대륙이동설을 펼쳤으나 1930년 베게너의 죽음과 함께 많은 과학자들의 반박에 밀려 대륙이동설은 고개를 숙이게 되었다.

The purpose of this study is to examine the scientific activities of scientists justifying Wegener's continental drift in the 20th century, which is explained as a revolutionary process in earth science, and methodologically analyze the strategy of proposing new scientific theories and how the process of theory selection is carried out. Previously, the Earth was a static model and only the vertical movement of the crust was considered. However, the theory of continental drift proposed horizontal movement of the crust as a dynamic model of the Earth, eliminating numerous problems. Therefore, this study seeks to explore the rational activities of numerous scientists until the current plate tectonics theory was formed. Additionally, the theory of continental drift is in conflict with the theory of Earth shrinkage, which is an existing static model. In other words, it deviates from the existing mechanistic world view by presenting a dynamic model in which the Earth is created and changes, as opposed to a static model in which the Earth is already completed, fixed, and unchanged. As a result, old geology was weakened and new geophysics was born. The theory of continental drift and continued exploration by subsequent generations of scholars brought about a revolution in earth science. This can be said to be a good subject of investigation as educational material for various methodologies for students in earth science education, and as educational material for changing students' worldview.
