Layers Of The Earth: What Lies Beneath Earth
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 Earths structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below. Although the rocks of the … See more There are two types of lithosphere: oceanic lithosphere and continental lithosphere. Oceanic lithosphere is associated with oceanic crust, and is slightly denser than continental lithosphere. See more Plate Tectonics The most well-known feature associated with Earths lithosphere is tectonic activity. Tectonic activity describes the interaction of the huge slabs of lithosphere … See more The cool, brittle lithosphere is just one of five great spheres that shape the environment of Earth. The other spheres are the biosphere (Earths living things); … See more Most tectonic activity takes place at the boundaries of these plates, where they may collide, tear apart, or slide against each other. The … See more Web23 Jul 2024 · The lithosphere is the solid outer part of the Earth. It includes the brittle upper portion of the mantle and the crust the planet’s outermost layers. The lithosphere is located below the atmosphere and above the asthenosphere. The asthenosphere is made of melted rock that gives it a thick sticky consistency.

Below the lithosphere lies the asthenosphere. Although solid, the asthenosphere has relatively low viscosity and shear strength and can flow like a liquid on geological time scales. peoplestrong recruit
