(一)中、低纬度大陆破碎之谜根据德国地球物理学家魏格纳提出的大陆漂移假说,距今三亿年以前,地球上只有一块陆地,在它的周围是一片广阔的海洋,大约在二亿年前,大陆开始分裂、漂移、逐渐形成今天这种海陆分布状态,引起大陆分裂并漂移的动力主要来自地球自转产生的离 (I) The Mystery of the Continent’s Crushing at Middle and Low Latitudes According to the continental drift hypothesis put forward by German geophysicist Wegner, only 300 million years ago, there was only one piece of land on the earth and a vast ocean around it. Before 200 million years ago, the mainland began to split and drift, gradually forming the current distribution of land and sea. The driving force that caused the mainland to split and drift mainly came from the Earth’s rotation
