The Earth's structure is typically described in terms of layers: the crust, the mantle, and the core. These layers can be further divided based on physical properties (like rigidity) or chemical composition. The Lithosphere is defined as the rigid outer layer of the Earth. It consists of the entire crust (continental and oceanic) and the uppermost, rigid part of the mantle, often called the lithospheric mantle.
Which one of the following best describes the Lithosphere ?
