Describe the relationship of the earth’s lithosphere to the asthenosphere.

Lithosphere floats on the top of Asthenosphere

The earth crust is made up of tectonic plates and these tectonic plates are always in flow. Together the earths crust and mantle beneath it is called lithosphere. On the other hand the area beneath the mantle is called the asthenosphere. Actually lithosphere is solid in nature and asthenosphere is semi solid or liquid nature. The lithosphere floats on the asthenosphere.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
