lithosphere(岩石圈)是地球最外层的刚性部分,包括地壳和上地幔顶部,平均厚度约100公里。它是板块构造理论中“板块”的主体。
The movement of tectonic plates occurs within the lithosphere.
(板块运动发生在岩石圈内。)
Scientists study the composition of the Earth's lithosphere to understand earthquakes.
(科学家通过研究地球岩石圈的组成来理解地震。)
拆分单词:litho-(希腊语“石头”)+ -sphere(球体、圈层)→ “石头圈” = 岩石圈。
