solid
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.
In the mantle, rocks are in a semi-solid state known as magma. The mantle is made up of solid rock that can deform and flow slowly over long periods of time due to the extreme heat and pressure found in this layer of the Earth.

The Earth's upper mantle is composed of solid rock that flows through liquid rock, also known as lava.

False. Weather is the current state of the atmosphere at a specific place and time, not the lithosphere. The lithosphere refers to the solid outer layer of the Earth that includes the crust and uppermost part of the mantle.
Well, it's made up of compressed rock. Another person asked this question and this is the answer: "The Earth's mantle, other than the uppermost hard, rocky layer, is composed of rock in a pliable solid state." Hope this helps and answers your question.

Solid
The crust is the outermost rocky layer, based on division by chemistry. The lithosphere is the outer rocky shell of the Earth, based on the physical state of the material (brittle). The lithosphere is a combination of the crust, and the brittle uppermost mantle.
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.
solid
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.
