Yahoo is part of Verizon Media. Asthenosphere lies beneath lithosphere and starts at about 100 to 200 kilometres below the surface. 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. It mainly consists of liquid mantle and that is why it is more mobile than lithosphere to move. The movement of lithosphere involves the movement of massive tectonic plates, which constitute the crust of the earth. ; Chemically, Earth can be divided into the crust, upper mantle, lower mantle, outer core, and inner core. * It is 100km thick. 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. Composition of the earth is not the same all the way but it varies a lot layer-by-layer. The asthenosphere is very plastic. Difference between Lithosphere and Asthenosphere, What is a Savings Bond and How Does It Work, Difference Between Army and Marines Basic Training, Top 10 Most Dangerous Air Hijackings in the World, What is Hypertensive Atherosclerosis Cardiovascular Disease. It comprises of the crust and the portion of the upper mantle that behaves elastically on time scales for thousands of years. Hence, it is actually asthenosphere which causes earthquakes to happen, rather than lithosphere itself.

Astenosphere: * Portion of upper mantle is called astenosphere. It is the highly viscous, mechanically weak and ductility-deforming region of the upper mantle of this planet. 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. How are crust and lithosphere different from each other? The very first difference between these two layers is there location and extend. Essentially, it is a difference in the degree of ductility.

Lithosphere starts from the surface of the earth and extends to approximately first 50 miles below towards the core of the planet.

The movement of this liquid mantle causes the movement in the tectonic plates of lithosphere, resulting in earthquakes.

The lithosphere–asthenosphere boundary (referred to as the LAB by geophysicists) represents a mechanical difference between layers in Earth's inner structure.Earth's inner structure can be described both chemically (crust, mantle, and core) and mechanically.The lithosphere–asthenosphere boundary lies between Earth's cooler, rigid lithosphere and the warmer, ductile asthenosphere. 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.

Lithosphere mainly consists of granite and basalt but more than 80 other elements are also found in the crust. Image Courtesy: tampabayliteningdiv1.weebly.com, Asthenosphere Two of such layers are lithosphere and asthenosphere, which interact with each other to make the appearing surface of this planet. ; The Crust. 6 − six =. The part of the upper mantle called the asthenosphere is ductile, and is the portion of the mantle on which the lithosphere 'floats'. It mainly consists of liquid mantle and that is why it is more mobile than lithosphere to move. The lithosphere is about 100 kilometers thick. Asthenosphere also originated from the Greek words, “asthenes” (meaning weak) and “sphaira” (meaning sphere). * It behave as brittle and rigid solid. You can change your choices at any time by visiting Your Privacy Controls. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. The solid plates move on the plastic asthenosphere. * Break on stress and cause earth quake because of rigid property. The core of the earth is not completely solid, with similar characteristics but it is constantly moving interacting combination of different layers of minerals. Lithosphere can be divided into two parts, the top of the mantle and the crust itself. This extend of lithosphere might vary at different locations. Asthenosphere Asthenosphere lies beneath lithosphere and begins at about 155 miles below the surface of the earth. As nouns the difference between lithosphere and asthenosphere Asthenosphere lies beneath lithosphere and begins at about 155 miles below the surface of the earth. Asthenosphere mainly comprises of ferro-magnesium silicates and lesser variety of combinations is found in this layer. Lithosphere Lithosphere originated from the Greek words, “lithos” (meaning rocky) and “sphaira” (meaning sphere), and forms the outermost shell of a rocky planet. The movement of this liquid mantle causes the movement in the tectonic plates of lithosphere, resulting in earthquakes. * Lithosphere is composed of uppermantle and crust. There are huge differences between these two layers of earth and they possess entirely separate characteristics. The lithosphere is more brittle and strong.
