Which of earth layers are the thickest?

Are convection currents found in the upper or lower mantle of earth?
The upper 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 .
What is is the meaning of Earth's 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.
