Answer 2

As a fraction show the relationship of the earth's thinnest layer and the thickest

• The solid outer crust, the mantle, the outer core, and the inner core are the four primary layers that make up the Earth. The crust is the thinnest layer among them, and the mantle is the thickest.
• The outermost surface is the crust of the Earth. The solid rock is only a very thin layer thick. It is the Earth's thinnest layer. Underneath the land, the crust is 5-35 km thick, while it is 1–8 km thick beneath the oceans.
• The crust of the Earth is its topmost layer, and depending on where it lies, it can range in thickness from 5 to 25 miles. The oceanic crust, the thinnest layer beneath the oceans, is only a few miles thick. The continental crust, which is about 25 miles thick and lies beneath the continents.
• Where the upper mantle has cooled beneath a relatively thin, ancient layer of oceanic crust, the oceanic lithosphere can be up to 100 kilometres thick. The thinnest edges of active continental rifts are where the continental lithosphere rests over the extremely hot, viscous upper mantle.
• Summary. Oceanic crust is both denser and thinner than continental crust. Oceanic crust is more mafic, while continental crust is more felsic. The crust is rather thin in comparison to the radius of the Earth.
