After the mantle, the next and last layer of the earths internal structure is the core, but the only sort of barrier that exists is a kind of transistion zone that serves as a linkage between the two layers.
Sand that has been run through a chemical processor of some kind so it is really pure and in its softest state.
No the earths core is not a cause of globel worming
layer 3 , network layer .
Earths lithosphere is made up of upper mantle. The earths lithosphere is broken into separate sections and it is called as tectonic plates or plate tectonics.
Lithosphere :)

STRATOSPHERE
the layer of rock that comprises 67% of earths mass

The earth thinnest layer is the crust.
The crust is the thinnest layer of the Earth.
Actually, the Troposphere Layer can be considered as Earth's first protective layer, because its well-the atmosphere's first layer. You can think of it that way to remember which is Earths first layer.
The layer below the earth's outer layer is mesosphere. It is the 3rd layer.
The earths crust is a part of the outermost layer.
