New research from Cornell and the Smithsonian Institution deepens the geological understanding of Earth’s continents by testing and ultimately eliminating a popular hypothesis about why continental an...
应地球科学领域国际著名期刊《地球物理学研究杂志》Journal of Geophysical Research（JGR）邀请，天津大学地球系统科学学院刘静教授自2020年12月31日起开始正式担任JGRSolid Earth的副主编（三年期）。
板块构造学说为解释地表观测到的几乎全部地质现象提供了动力学机制，如，板块相对运动机制，远离彼此的大陆板块上相似古生物地理分区的形成，以及大陆穿过不同特定古气候带的原因等等。这些运动通过地幔下降和上涌分别对应的板块俯冲和海底扩张实现。板块运动本质上是地幔对流造成的。

Scientists earlier birth date Earth tectonic plates
2020/6/5
Geophysicists funded by the National Science Foundation have reported that Earth's ever-shifting, underground network of tectonic plates was firmly in place more than 4 billion years ago -- at least a...

Scientists early Earth water world’ exposed ocean crust
2020/3/13
The Earth of 3.2 billion years ago was a "water world" of submerged continents, geologists say, after analyzing oxygen isotope data from ancient ocean crust now exposed on land in Australia. The findi...
