Another name for the lower mantle is called the asthenosphere.
Working outwards from the centre: The Earth is believed to be formed of an inner core, outer core, inner mantle, outer mantle, and the crust. The mantle is two thousand miles thick and makes up more than three-quarters of the Earth's volume.
The lower mantle is older and cooler than the upper mantle. Thank you for reading this I'm comment if you like one direction(: hehe
