* Break on stress and cause earth quake because of rigid property. Astenosphere: * Portion of upper mantle is called astenosphere. Required fields are marked *, Prove You\'re Human * Lithosphere originated from the Greek words, “lithos” (meaning rocky) and “sphaira” (meaning sphere), and forms the outermost shell of a rocky planet. Asthenosphere Asthenosphere lies beneath lithosphere and begins at about 155 miles below the surface of the earth. There are huge differences between these two layers of earth and they possess entirely separate characteristics. The definition of the lithosphere is based on how Earth materials behave, so it includes the crust and the uppermost mantle, which are both brittle. Asthenosphere mainly comprises of ferro-magnesium silicates and lesser variety of combinations is found in this layer. 6 − six =. ; The Crust. The solid plates move on the plastic asthenosphere. It is the highly viscous, mechanically weak and ductility-deforming region of the upper mantle of this planet. To enable Verizon Media and our partners to process your personal data select 'I agree', or select 'Manage settings' for more information and to manage your choices. Two of such layers are lithosphere and asthenosphere, which interact with each other to make the appearing surface of this planet. Find out more about how we use your information in our Privacy Policy and Cookie Policy. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. It mainly consists of liquid mantle and that is why it is more mobile than lithosphere to move. It mainly consists of liquid mantle and that is why it is more mobile than lithosphere to move. Mechanically, the earth’s layers can be divided into lithosphere, asthenosphere, mesospheric mantle (part of the Earth’s mantle below the lithosphere and the asthenosphere), outer core, and inner core. In context|geology|lang=en terms the difference between lithosphere and asthenosphere is that lithosphere is (geology) the rigid, mechanically strong, outer layer of the earth; divided into twelve major plates while asthenosphere is (geology) the zone of the earth's upper mantle, below the lithosphere. Composition of the earth is not the same all the way but it varies a lot layer-by-layer. Lithosphere mainly consists of granite and basalt but more than 80 other elements are also found in the crust. This extend of lithosphere might vary at different locations. ; Chemically, Earth can be divided into the crust, upper mantle, lower mantle, outer core, and inner core.

The lithosphere is more brittle and strong. * It is 100km thick. The core of the earth is not completely solid, with similar characteristics but it is constantly moving interacting combination of different layers of minerals. How are crust and lithosphere different from each other? The asthenosphere is very plastic. It comprises of the crust and the portion of the upper mantle that behaves elastically on time scales for thousands of years. * It behave as brittle and rigid solid. It is the movement of lithosphere which causes earthquakes on the surface. The upper part of lithosphere is extremely solid but it also includes the uppermost part of the mantle, which is in liquid form and mobile. The movement of this liquid mantle causes the movement in the tectonic plates of lithosphere, resulting in earthquakes. Asthenosphere lies beneath lithosphere and begins at about 155 miles below the surface of the earth. The movement of lithosphere involves the movement of massive tectonic plates, which constitute the crust of the earth. Asthenosphere lies beneath lithosphere and starts at about 100 to 200 kilometres below the surface. Asthenosphere also originated from the Greek words, “asthenes” (meaning weak) and “sphaira” (meaning sphere). The part of the upper mantle called the asthenosphere is ductile, and is the portion of the mantle on which the lithosphere 'floats'. * Lithosphere is composed of uppermantle and crust. The lithosphere is about 100 kilometers thick. Image Courtesy: tampabayliteningdiv1.weebly.com, Asthenosphere Your email address will not be published. As nouns the difference between lithosphere and asthenosphere The very first difference between these two layers is there location and extend. Lithosphere starts from the surface of the earth and extends to approximately first 50 miles below towards the core of the planet.
