Answer:
The lithosphere is the solid, outer part of the 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.

Step-by-step explanation:
The lithosphere is the outer solid shell of the Earth As the cooling surface layer of the Earth’s convective system, the lithosphere thickens over time. It is fragmented into relatively strong pieces or plates, which move independently relative to one another. These lithospheric movements are described as plate tectonics. The lithosphere includes the crust and, below, the uppermost layer of the mantle; it floats on the weaker asthenosphere. There are two types of lithosphere:
- Oceanic lithosphere, which is associated with Oceanic crust
- Continental lithosphere, which is associated with Continental crust
