Lithosphere. It extends to a depth of about 60 mi (100 km). It is broken into about a dozen separate, rigid blocks, or plates ( see plate tectonics ). Slow convection currents deep within the mantle, generated by radioactive heating of the interior, are believed to cause the lateral movements of the plates
The depth of the lithosphere varies widely by location. The range of depth is from 40 kilometers to 200 kilometers. subducted lithosphere ranges upto 400km,which is the maximum depth it is being infered. 7 people found this useful.

Lithosphere. The lithosphere extends from the surface of Earth to a depth of about 44 – 62 mi (70 – 100 km). This relatively cool and rigid section of Earth is believed to “float” on top of the warmer, non-rigid, and partially melted material directly below.
The lithosphere extends from the surface of Earth to a depth of about 44-62 mi (70-100 km). This relatively cool and rigid section of Earth is believed to “float” on top of the warmer, non-rigid, and partially melted material directly below.
The primary difference between the lithosphere and asthenosphere is the depth below the Earth’s surface to which each of these layers extend. The lithosphere starts from the surface, and on average, extends to a depth of 100 km below the surface.
Continental lithosphere, which is associated with continental crust (mean density of about 2.7 grams per cubic centimeter) The thickness of the lithosphere is considered to be the depth to the isotherm associated with the transition between brittle and viscous behavior.
Jan 19, 2019 · The lithosphere is the outermost shell of the Earth, separating the crust from the upper mantle. Movements of plates in the lithosphere formed giant mountains like Mount Everest. Lithospheric plates are more commonly known as tectonic plates.
Geologists use the term as the name for the layer of the Earth extending from the surface to a depth of around 80 to 120 miles, depending on location, in which rocks are relatively brittle and rigid. This is the definition we will explore here.
The Lithosphere of the earth is the outer rigid, solid and hard section of the earths structure which is composed of the crust and upper part of the mantle.
The Lithosphere–asthenosphere boundary (referred to as the LAB by geophysicists) lies between Earth’s cooler, rigid lithosphere and the warmer, ductile asthenosphere. The actual depth of the boundary is still a topic of debate and study, although it is known to vary according to the environment.
Asthenosphere, zone of Earth’s mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) below Earth’s surface.
• The mineral composition of lithosphere is varied as it contains more than 80 minerals whereas Asthenosphere is mainly comprised of silicates of iron and magnesium. • The depth of the lithosphere is about 100 kilometers, whereas the depth of Asthenosphere is 400-700 kilometers.
