The characteristics of the asthenosphere are that it is composed of semi-fused and solid materials. The asthenosphere is responsible for the renewal and expansion of the ocean floor. Asthenosphere The asthenosphere is the upper zone of our Earth’s mantle. Located below the lithosphere, approximately between 30 and 130 kilometres deep. It is formed or composed of …

The asthenosphere is solid upper mantle material that is so hot that it behaves like plastic and can flow. The lithosphere rides on the asthenosphere. The asthenosphere is solid but it can flow, like toothpaste. The asthenosphere and Lithosphere constitute the utmost concentric layers of …

2016年6月12日 · The asthenosphere is a layer (zone) of Earth’s mantle lying beneath the lithosphere. It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid.

2016年4月15日 · Asthenosphere is more yielding to perristent stress and softer than the lithosphere. It is a low-viscosity shell Asthenosphere is in-between lithosphere and a part of the upper mantle. It extends. from about 100 km, to nearly 700 km. The broad classification for the Earth's interior, based on mechanical properties, is lithosphere, asthenosphere,mesosphere, …

2015年12月13日 · Asthenosphere is a layer of the Earth which lies below the crust and at the upper part of the mantle. This is where the high pressure and pressure allows solid rock to flow slowly,or change in shape. (plasticity)

The interior of the earth can be divided into 3 different layers – crust, mantle, and core. The crust is the outermost layer of the earth, and the core is the innermost layer of the earth, located at a depth of 2900 Km. This article briefly throws light on these 3 different interior layers of the earth. Geography is a very important component of the IAS Exam. Structure of the Earth (UPSC ...

2016年4月30日 · The plastic asthenosphere is further down. The Mohorovicic Discontuity is the boundary between the crust and mantle, where the basalt present in the crust gives way to heavier silicate rocks such as periodotite and dunite, which are characteristic of the upper mantle.

It boils down to temperature: the asthenosphere is warm enough to deform plastically, while the lithosphere is colder and rigid. You can pull warm taffy easily, whereas cold taffy is hard to pull and likely to break if you try. So it is with the rock in the upper mantle, except that "warm" in this case is about 1300°C or more. The boundary between the lithosphere and the asthenosphere …

2016年3月25日 · There is no liquefied part in the asthenosphere that is in-between lithosphere above and upper mantle below. It is a low-viscosity shell. It is softer than lithosphere in reacting to stress. Asthenosphere extends from about 60 miles down to about 450 miles. Both primary and secondary seismic waves are propagated through asthenosphere.

2018年3月2日 · Geosphere, lithosphere, crust, mesosphere, mantle, core, asthenosphere, and tectonic plates. 1. Geosphere:- It is the solid part of the earth that extends from center of the core to the surface of the earth. Lithosphere:- The cool rigid outer layer of the earth which includes the crust and the upper core of the mantle. Crust:- Made up of many light elements and is the …
