The state of matter in the lower mantle is stiff plastic (solid).
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
upper mantle and the lower mantle
The upper mantle and the lower mantle.

The mesosphere
The middle mantle is just above the lower mantle.
The Lower Mantle
The lower mantle is beneath the crust.
The upper mantle and the lower mantle.
The lower mantle is the portion of the Earth's mantle layer that extends from a depth of 670 km to 2798 km from the surface. Minerals present in the rock of the upper mantle become unstable at these depths. Little is known about the lower mantle other than that seismic waves indicate it is fairly homogenous in lithology and therefore density.

The upper mantle is harder than the lower mantle
Well there is the crust, upper mantle, lower mantle, outer core, and the inner core. So, the lower mantle is the 3rd one down.
