The lower mantle is solid, with a viscosity that is higher than the upper mantle. It is composed mainly of silicate minerals, such as perovskite and bridgmanite, which contribute to its solid state at high pressures and temperatures.
The uppermost part of the mantle exists in a solid state primarily due to the high pressures and temperatures within the Earth. Despite being hot enough to melt rock, the immense pressure prevents the material from transitioning into a liquid state. Additionally, the composition of the mantle, which is rich in silicate minerals, contributes to its solid nature under these conditions. This solid layer plays a crucial role in tectonic processes and the movement of the Earth's lithosphere.
The Earth's upper mantle is composed of solid rock that flows through liquid rock, also known as lava.
The lower mantle remains solid due to high pressure, which increases the melting point of minerals. The pressure at such depths is so immense that it keeps the minerals stable in a solid state despite the high temperatures.
solid
The lower mantle is in a solid state of matter. It is composed mainly of silicate minerals, which can withstand high pressure and temperature, maintaining a solid form despite the intense conditions present at that depth within the Earth.
The lower mantle is solid and composed of silicate minerals like magnesium and iron oxides. It is located beneath the upper mantle and extends from 660 to 2,900 kilometers below the Earth's surface. The lower mantle experiences high pressure and temperature conditions, contributing to its solid state.
The lower mantle is primarily solid, although some areas may experience partial melting to create magma. The solid nature of the lower mantle is due to high pressure, which helps keep the minerals in a solid state despite high temperatures.

Me because I am so hot
The lower mantle is in the solid state. It is composed primarily of silicate minerals in a crystalline structure, which makes it capable of transmitting seismic waves.

The word 'cool' best characterizes the lower mantle.
solid
it is an extremely viscose liquid, so viscose one could call it a semi-solid liquid.
