GEOLOGY

Detailed explanation-1: -The lithosphere is the solid, outer part of Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.

Detailed explanation-2: -In plate tectonics, Earth’s outermost layer, or lithosphere-made up of the crust and upper mantle-is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.

Detailed explanation-3: -The upper mantle is a layer of the interior of the Earth. It exists between the crust and the transition zone. The very uppermost portion of the mantle is part of the lithosphere, a layer that includes the crust. This layer is hard and brittle and is where tectonic plates exist.

Detailed explanation-4: -Rheology. Earth’s mantle is divided into two major rheological layers: the rigid lithosphere comprising the uppermost mantle, and the more ductile asthenosphere, separated by the lithosphere-asthenosphere boundary.
