板块的构造基础 Based on plate tectonic

板块的构造基础 Based on plate tectonic

基本论点： Basic argument
地球外部的岩石圈并非完整的一块，它被构造活动带分割成许多块体，称为板块
岩石圈板块漂浮在软流圈之上，不断地生长、移动、消亡。The lithosphere outside the Earth is not a complete one piece, it was split into many blocks because of the tectonic activity, known as the Plate。
Lithosphere plates floating on the asthenosphere,constantly grow, move and demise.
板块边界是地球表面最活动的地带，绝大多数地震、火山分布于活动带上，而板块内部则是相对稳定的地区。
The most active area of the Earth surface is plate boundary,where most earthquakes and volcanic distribute on, while the region within the plate is relatively stable.
板块运动是形成地表各种构造形变根本原因。Plate tectonic movement is the root cause of various of the Earth surface structural deformation
形成原因：Causes:

大陆漂移说的内容：That the content of continental drift
魏格纳大陆由较轻的刚性的硅铝层组成，它漂浮在较重的粘性的硅镁质洋底之上，硅铝层原曾覆盖过地球的整个表面，随后由于皱缩使其面积减小而厚度增大，到古生代末期和中生代初期演变成一整块联合古陆（即泛大陆），相应的海域只有一个，即泛大洋。Eugene mainland by the lesser of the Si-layer rigid, floating in the heavier viscosity of the ocean floor above-Si-Mg, Si-layer has covered the entire surface of the Earth, and then because of its shrinkage Reduce the increasing size and thickness, the late Paleozoic to Mesozoic and early evolution into a block joint ancient land (that is, pan-continent), the corresponding area there is only one, namely the Pan-Ocean.
中生代开始，特别是侏罗纪时，这个大陆裂开、解体，并发生水平移动，于是形成今天的各大洲和各大洋。大西洋和印度洋是在大陆解体、漂移过程中的产物，原来的泛大洋缩小为今日之太平洋Mesozoic, especially the Jurassic, the continent split and disintegration, and in the level of movement, therefore formed todays continents and oceans. Atlantic and Indian Ocean in the disintegration of the mainland, the drift in the process of product, the original Pan-Ocean narrow for todays Pacific.
大陆漂移的方向：Continental drift in the direction
一是自地球两极向赤道的离极移动如两亿多年前聚集在南极的南半球诸大陆向北四散漂移，并在非洲、印度和欧亚大陆之间形成阿尔卑斯—喜玛拉雅褶皱山系First, since the two poles to the equator of the earth from the very mobile as more than 200 million years ago gathered in the southern hemisphere all the Antarctic continent scattered northward drift, and in Africa, India and Eurasia formed between the Alps - Himalaya Mountains fol.另一是向西漂移如美洲大陆西移因太平洋底的抵抗而在大陆西线形成科迪勒拉和安第斯山系，在大陆的东部则脱落下一些落伍的碎块形成岛屿，Another is the westward drift as a result of the American continent west Pacific at the end of the resistance in the mainland and the Western form of the Andean Cordillera and in the eastern part of the mainland while falling backward under some of the fragments formed islands.如在亚洲大陆后方的日本、琉球、台湾、菲律宾岛，在澳洲大陆东面的新西兰岛，在中美洲东面的古巴、安德列斯群岛，在非洲大陆东面的马达加斯加岛，印度东侧的锡兰岛，以及尾随在南美洲南端的马尔维纳斯群岛等，If the rear of the Asian mainland Japan, Okinawa, Taiwan, the Philippines Island, east of the mainland in Australia, New Zealand Island, east of Cuba in Central America, Andreas Islands, the African continent in the east of Madagascar Island, east India The Ceylon Island, followed in South America and the southern tip of the Malvinas Islands.并且掉队愈远，岛屿愈小And from the more distant, smaller islands.
之后的进展：After the progress
魏格纳的学说曾经盛行一时。但是，硅镁层实际是刚性的，硅铝质大陆不能在其上航行，人们不了解有什么机制能使大陆发生漂移。Eugene was the prevailing theory 1:00. However, the real-Si-Mg layer is rigid, silicon aluminum on the mainland can not be in their voyage, people do not know what mechanism can drift in the mainland.
大陆漂移说本身的依据还不足，某些证据可作另外的解释，尤其是缺乏定量的证据，不易使人信服。加之传统的固定论_强大，大陆漂移说在一些地质学和地球物理学权威的极力反对之下，未能得到广泛的支持而逐渐衰落Continental drift that itself is also the basis for the lack of evidence for some other e*planation, especially the lack of quantitative evidence, not convincing. In addition, the traditional fi*ed on the powerful, continental drift that in a number of Geology and Geophysics under the authority of the strong opposition, failed to receive broad support and gradually fading.
