So the Asthenosphere and the Mesosphere lie between the Crust and the Mantle. After the Mantle comes the Outer Core, which begins at a depth of 2,890 km and goes on until 5,150km.

The mechanism facilitating the smooth movement of the oceanic lithosphere over the underlying asthenosphere (upper mantle) remains poorly understood. Recently, researchers from Japan investigated ...

The lithosphere is Earth's outermost layer, composed of the crust and the upper part of the mantle. The layer is divided into chunks called tectonic plates.

Earth's mantle is 2,900 km thick and is broken down into 3 main zones, the lithosphere, asthenosphere, and mesosphere.

There are five primary physical layers around the earth, namely the lithosphere, asthenosphere, mesosphere, outer core, and inner core. The lithosphere forms the uppermost layer of the Earth and ...

Additionally, they note, "At greater depths, the lithosphere-asthenosphere boundary (LAB) represents a first-order structural discontinuity that accommodates differential motion between the ...

If we subdivide the Earth based on rheology, we see the lithosphere, asthenosphere, mesosphere, outer core, and inner core.

Although a rigid lithosphere (about 100 km of crust and uppermost mantle) moving over a weaker asthenosphere (a few hundred kilometres of more deformable rock) is a widely accepted aspect of plate ...
