The zone below the lithosphere
Web29 Nov 2024 · The upper mantle, along with the crust, comprises what is called the lithosphere. The lithosphere is approximately 120 miles or 200 kilometers thick. This is where the tectonic plates exist. Below the lithosphere, you'll find the asthenosphere. The lithosphere essentially glides over the asthenosphere as a series of tectonic plates. Web20 Mar 2013 · A mysterious layer lies beneath Earth's massive tectonic plates.

WebThe low-velocity zone (LVZ) occurs close to the boundary between the lithosphere and the asthenosphere in the upper mantle. It is characterized by unusually low seismic shear wave velocity compared to the surrounding depth intervals. This range of depths also corresponds to anomalously high electrical conductivity. 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.
