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 our earth. The asthenosphere encompasses much of the upper mantle of the earth. Then, the lithosphere comprises the uppermost mantle as well as the overlying crust.
What are the characteristics of the asthenosphere? - BYJU'S
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 solid and semi – fused materials that allow continental drift. The asthenosphere is composed of rock material. It is formed by iron and magnesium silicates.

The asthenosphere is the upper portion of Mantle. It is the chief source of magma that finds its way to the surface during volcanic eruptions. The crust and the uppermost part of the mantle are called the lithosphere. The major constituent elements of the mantle are Silicon and Magnesium and hence it is also termed as SIMA
The Three Layers Of The Earth, Inner Core, Outer Core - BYJU'S
Mantle. Mantle is the widest section of the Earth. Its thickness is approximately 2,900 km. The mantle is mainly made up of semi-molten rock known as magma.

The atmosphere is the layer of gases surrounding a planet. Know about atmosphere layers, composition of atmosphere and about each layer @BYJU'S.
Q. With reference to the asthenosphere, consider the following ...
The asthenosphere is a semi-solid or semi-molten, soft and fluid layer. It is found below the lithosphere, between approximately 80 and 200 km below the earth’s surface. It is responsible for driving plate tectonics motion. The lithospheric plates are hard, rigid shells and sit …
Earthquake - Protection, Definition, Causes, Effects, Precaution
These movements result from interactions between tectonic plates, large sections of the Earth’s crust that float on the semi-fluid layer known as the asthenosphere. When stress along plate boundaries becomes too great, rocks along the boundaries break and slip, releasing stored energy and generating seismic waves.
Q. Consider the following statements: - BYJU'S
The asthenosphere is the layer of earth located in the upper portion of the mantle, beneath the lithosphere. It is considered to be extending up to 400 km. It is the main source of magma that finds its way to the surface during volcanic eruptions. The characteristics of the asthenosphere are that it is composed of semi-fused and solid materials ...
Q. Consider the following statements with respect to the interior ...
The upper portion of the mantle is called the asthenosphere. The word astheno means weak. It is considered to be extending up to 400 km. It is the main source of magma that finds its way to the surface during volcanic eruptions.
Which of the following layers of the Earth has the highest ... - BYJU'S
The correct option is A. Inner core. The innermost layer has the highest temperature. The crust is the outermost layer of the Earth. The layer be
