Asthenosphere – the layer of the earth that is in a semi-molten state

Asthenosphere – the layer of the earth that is in a semi-molten state You can be asked to name the stratum of the earth that is semi-molten in a geography test question.

Prior to anything else, it’s critical to comprehend how the earth is built. The layers that make up the earth’s structure are as follows:

Crust: Continental Crust, Oceanic Crust
Mantle: Upper Mantle, Lower Mantle
Core: Outer Core, Inner Core

identify the layer of the earth that is in a semi-molten state

The layer of the earth that is in a semi-molten state is called asthenosphere found in the upper mantle. The upper mantle extends from the crust to a depth of about 410 kilometers. The asthenosphere is the denser, weaker layer beneath the lithospheric mantle. It lies between about 100 kilometers (62 miles) and 410 kilometers (255 miles) beneath Earth’s surface. The temperature and pressure of the asthenosphere are so high that rocks soften and partly melt, becoming semi-molten.
