Explanation:
The asthenosphere is located below the lithosphere and is composed of the upper mantle.
The rocks that form the Earth's mantle are mostly silicates. Another type of rock that is usually observed in this layer is magnesium oxide, accompanied by other elements such as iron, aluminum, calcium, sodium and potassium.
The answer is: The mantle.
Asthenosphere is the upper mantle part below the lithosphere. This layer consist of chemicals and minerals.
Asthenosphere is the upper mantle part below the lithosphere. Also considered as the reason behind the tectonic plates movements.it is formed by rocks containing olivine mineral and pyroxene and also composed of peridotite.
Asthenosphere is part of the upper mantle. Although earths mantle mostly consist of silicates but asthenosphere also consist of magnesium oxide, olivine mineral and elements such as iron, calcium, sodium.
Therefore, it can be said that asthenosphere is mantle upper part.
