Question

What is the partially molten layer of Earth called

Answer 1

The partially molten layer of the Earth is called the **asthenosphere**. This layer is located just below the lithosphere and extends from about 100 kilometers (62 miles) to 700 kilometers (435 miles) beneath the Earth's surface. The asthenosphere is composed of mantle material that is capable of flowing slowly over geological timescales, allowing for the movement of tectonic plates above it.
