一、地震是地壳构造运动的反映地球是从太阳喷射出来的物质,在形成星子、陨石后集聚而成,它生成之后一直在变动,地质史的早期其变动程度是惊人的,沧海桑田一语并不过分,并已由地质学家所共识。地球在地质史初期只有一个泛大陆(包括东、西大陆)和一个大洋——太平洋,然而它们并不恒定,却在2亿年前的阿尔卑斯期的构造运动中,把泛大陆一分为二了,这就是魏格纳所提出的“大陆漂移”。于是又出现了大西洋、印度洋。喜马拉雅原来是海域,
First, the earthquake is a reflection of crustal movement Earth is the material ejected from the sun, after the formation of astronomical, meteorite accumulation formed, it has been after the change, the early changes in geological history is staggering, Not too much, and has been agreed by geologists. The Earth had only one pan-continental (including the east and west continents) and one oceans-Pacific Ocean at the beginning of its geological history. However, they are not constant. However, in the tectonic Alps period of 200 million years ago, the earth was divided into two parts And this is what Wagner has put forward as “the mainland drift.” Then appeared the Atlantic, Indian Ocean.
