Due to Gaia’s large size, it dominated the collision and began to form the shape of Earth as we know it today. Meanwhile, much of the debris from the collision consolidated and produced the Moon. Though this has been the dominant idea for the Moon’s formation, no evidence of Theia ...
12. 答案:A 第二段中,"This" 指代的是前文提到的 "a big collision (碰撞) took place in the sky, about the size of Mars, hit the Earth",即 Theia 撞击地球。 13. 答案:B 文章提到,科学家通过研究月球岩石中的一种特殊矿物质,更清晰地了解了 Theia 的性质,从而推断出月球的年龄。反馈...
Theia, which did not survive the collision except that it now makes up large parts of Earth and the moon was growing and probably would have become a planet if the crash had not occurred, Young said. Young and some other scientists believe the planet was approximately the same size as the...
Yuan said that when Theia smashed into proto-Earth, it was traveling at more than six miles a second, a speed that allowed some of it to penetrate "very deep into the Earth's lower mantle." Avideo developed by the teamsimulating this process illustrates how clumps of Theia's mantle tens...
