Talk:Internal structure of Earth

Our table shows the crust extending for 35 km under all definitions. But our first sentence in the Crust section says 5-70 km. Can anyone who knows the nuances (I do not) make this coherent? Jmacwiki (talk) 14:45, 26 March 2022 (UTC)

The picture showing the cross section of Earth's lithosphere is no longer accurate. A fifth later of the lithosphere has been discovered within the core. It is a solid sphere of iron geologists are calling the innermost core. 2607:FEA8:99C0:61C0:1BA:4E9A:C03F:4C59 (talk) 19:09, 22 February 2023 (UTC)

The first sentence reads "The internal structure of the Earth are the layers (etc.)". Shouldn't it be "is" the layers? English isn't my first language but I know the subject of the verb "be" is structure, nor layers. Further down in the article the verb be after the same subject is indeed "is", not "are". To me there is a grammar mistake here, if I am not mistaken myself, in which case I wouldn't mind an explanation why. Onaryc2024 (talk) 13:25, 13 May 2025 (UTC)
