英语长难句分析？

Question

Another line of evidence that Wegener found convincing was the occurrence on several continents of glacially striated rocks directly overlying sediments deposited in an arid climate.

主干我知道是Evidence Was occurrence
On several…到句尾部分的成分怎么划分呢

Answer 1

您好!
这个句子的第一层结构是Another line of evidence was the occurrence。
that wagener found convincing 是一个定语从句，修饰先行词 evidence。
on several continents of glacially striated rocks 是后置定语，修饰 the occurrence
directly overlying sediments deposited in an arid climate 后置定语修饰rock。
其中，deposited in an arid climate 后置定语修饰sediments。
句子的意思是：wagener发现的另一个令人信服的证据是，在几个大陆上，在干旱气候下沉积的沉积物上有冰川纹状的岩石。
望采纳!
