地球内部因放射而产生的热量为板块运动、大陆漂移、造山运动和地震提供了能量。
Earth's internal heat, fueled by radioactivity, provides the energy for plate tectonics and continental drift, mountain building, and earthquakes.
1912年,阿尔弗雷德·魏格纳在一个被称为“大陆漂移”的理论中提出,地球上的大陆是可移动的。
In 1912, Alfred Wegener proposed, in a widely debated theory that came to be called continental drift, that Earth's continents were mobile.
例如,斯蒂芬·杰伊·古尔德认为,大陆漂移理论之所以被否决,是因为它没有解释大陆是如何穿过明显很坚固的海底的。
Stephen Jay Gould, for example, argues that continental drift theory was rejected because it did not explain how continents could move through an apparently solid oceanic floor.
魏格纳提出了大陆漂移说
Wegener研究大陆漂移的设想。
为什么要煞费苦心地拿板块学说和大陆漂移来进行类比?
Why this elaborate analogy with plate tectonics and continental drift?
大陆漂移、海底扩张是地球膨胀的直接结果。
The earth's expansion may directly result in continent drift and seafloor spreading.
一些作家已经提议也许大陆漂移引起两极漫游。
A few writers have suggested that perhaps continental drift causes polar wandering.
大陆漂移雕塑了地壳的外观,使现在大陆形成。
Massive segments or plates of the crust move over the mantle in the process of continental drift.
然而,到1946年,对大陆漂移说的战斗进行得如火如荼。
By 1946, however, the battle over continental drift was in full swing.
起初,科学家们嘲笑魏格纳有关大陆漂移的想法,不愿认真考虑。
At first scientists laughed at Wegener's idea about floating continents and would not take it seriously.
四千至五百万年前,印度大陆漂移与欧亚大陆发生碰撞,喜马拉雅山脉隆起。

袋鼠附近的一个标牌上面写着4000万年前大陆漂移的“不敬”言论,几乎天天都有污损。
A signpost near the kangaroos, making the sacrilegious claim that the continents shifted 40m years ago, used to be defaced almost daily.
当我还是一名大学生时,曾向一位地理学教授请教说,“你能给我们谈谈大陆漂移的方式吗?”
When I was an undergraduate, I went to the professor of geology and said, "Would you talk to us about the way that continents are drifting?"
直到在非洲和南美洲发现了几乎完全同类的动物化石,科学家们才接受了大陆漂移假说。
The scientists didn't accept the hypothesis of continental drift until almost identical fossils of animals were found both on Africa and South America.
七千万年前,印度大陆位于赤道之南,按照大陆漂移学说的标准,印度大陆头朝北快速移动。
Seventy million years ago, India lay south of the Equator. It was headed north, though, and by continental-drift standards, it was moving fast.
首先对地幔对流、大陆漂移和地震起源的机制做了尝试性分析,给出一个简单的力学解释。
A tentative analysis of the mechanism of mantle circulation flow, continent drifting and earthquake origin is first clearly made, giving a simple mechanics-based explanation of the nature.

The Theory of Continental Drift has had a long and turbulent history since it was first proposed by Alfred Wagener in 1910.
