This implies to determine when and how modern plate tectonics began. Today, the tectonic regime is dominated by mobile-lid tectonics including deep and cold subduction. However, in the early Earth (4.5 to 2 Ga) stagnant-lid tectonics may also have occurred. The study of high pressure–low ...
Plate tectonics is an expansion over the previous theory of Continental Drift proposed by Alfred Wegner in 1912. Wegner correctly identified that the Earth's landmasses were moving, but there were some flaws in his theory. For example, he proposed that the continents themselves were moving and ...
现在的解释就是很久前两个大陆是相连的,所以有一样的动植物群,后面由于板块运动(plate tectonics),陆地分开,上面的生物就往不同的方向去演化了。同一个物种可能从一个地方开始出现,后面由于偶然机会找到适合自己生存的环境,占地为王,分成了不同的群体,像南美洲和非洲大陆中间隔的海,使得两个陆地上的生物基本很难...
