Web26 Feb 2024 · The atmosphere itself rises to about 10,000 kilometers in height and is divided into four zones. The troposphere, where about three-quarters of all atmospheric mass can be found, stretches from about 8 to 14.5 kilometers above the earth's surface. Beyond this lies the stratosphere, which rises to 50 kilometers above the planet. WebThe 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. The lithosphere is the most rigid of Earth’s layers.
