人们常用坚如磐石来形容大地的稳定,用海枯石烂来形容海洋和山脉的永恒,但是,近来频频发生的地震使人们开始怀疑脚下的大地是否稳定,遮天蔽日的火山喷发也使人们疑惑雄伟的山脉是否永恒。实际上,随着地球科学的迅速发展,人们逐渐认识到,脚下的大地并不是稳固不变的,而是处在不断的运动之中。科学家提出了板块构造理论,来解释地球上的火山、地震的发生,诠释沧海桑田的变迁。
Rocks are often used to describe the stability of the earth. The ebb and flow of rocks and sea are used to describe the eternal sea and mountains. However, frequent earthquakes have recently led people to wonder whether the earth beneath them is stable or not. Whether the mountains are eternal. In fact, with the rapid development of earth science, people gradually come to realize that the earth underneath is not stable but is in continuous movement. Scientists proposed plate tectonics theory to explain the earth’s volcanoes, earthquakes occurred, interpretation of the vicissitudes of life.
