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.

∙ 9y agoThe lower mantle is the deeper part of the mantle. It is a thin sheet like layer that lies between the upper mantle and the core. The lower mantle seems to be fairly seismically uniform.

How many layers in earths mantle?
there are 7 layers in earths mantle.
What are facts about earths upper mantle?
Temperature is about 2000 to 3000 degrees celsius maybe less.The mantle is hot but not the hottest layer.It is is the second layer of the Earth. The mantle is the thickest layer of the earth, it is the layer of the earth beneath the crust.Upper mantle and Lower mantle are the two parts of the mantle, The lower mantle is deeper and denser than the upper mantle .

Earths lower mantle lies just below the?
Upper Mantle. This is also called the Asthenosphere
What lies below Earths Lower Mantle?
From the outside into the Earth. It goes Crust, Upper Mantle, Mantle, Outer Core, and Inner Core
What is the mechanical layer of earths that is solid rock and moves the least?
mesosphere

The Earth's mantle is about 2,890 km (or 1,800 mi) thick.
What is crust and upper mantle of the EARTH?
The upper mantle is in between the lower mantle and the earths crust Crust- the outer most solid shell of the earth. The Uppermost mantle and the earth's crust form the lithosphere.
