The inside of Earth is structured in layers primarily due to the varying temperatures and compositions of the core and mantle. The core, which is extremely hot, generates heat through radioactive decay and residual heat from Earth's formation, leading to a molten outer core and a solid inner core. In contrast, the mantle, though hot, remains in a semi-solid state due to lower temperatures and pressures, allowing for convection currents that drive plate tectonics. This temperature gradient is crucial in shaping the geodynamic processes that govern Earth's geology.
The lower mantle is one of the layers in the Earth's interior, located between the upper mantle and the outer core. It extends from a depth of about 410 to 660 kilometers below the Earth's surface. The lower mantle consists of solid rock material that experiences high pressure and temperatures.

Convectoin
Inside the Earth, there are several different layers: the inner core, outer core, mantle, and crust. The inner core is solid and made mostly of iron and nickel, while the outer core is liquid. The mantle is composed of hot, flowing rock, and the crust is the Earth's thin, solid outermost layer where we live.
Different temperatures inside the Earth lead to the formation of various structures, such as magma chambers where molten rock accumulates, as well as crystal growth in minerals under high temperatures and pressures. Additionally, temperature variations can cause thermal expansion and contraction, leading to the formation of fractures and faults within the Earth's crust.
The temperature of the Earth's mantle is higher than the temperatures of the outer layers, such as the crust, but lower than the core.

The Mantle
The lower mantle is one of the layers in the Earth's interior, located between the upper mantle and the outer core. It extends from a depth of about 410 to 660 kilometers below the Earth's surface. The lower mantle consists of solid rock material that experiences high pressure and temperatures.
H'm, i think it is either mantle of mantle and the crust of earth combined .so it is probably mantle
Convection currents form inside the Earth due to the temperature difference between the core and the mantle. The heat from the core causes the rock in the mantle to become less dense and rise towards the surface, while cooler rock sinks back down. This continuous cycle of rising and sinking rock creates convection currents that play a key role in driving the movement of tectonic plates.
the mantle
The mantle of the Earth can reach temperatures between 1,292°F to 7,652°F, depending on the depth and location within the mantle.
Diamonds are formed deep within the earth's mantle.
The source of heat in the mantle primarily comes from the decay of radioactive elements like uranium, thorium, and potassium. This process releases energy in the form of heat which contributes to the high temperatures within the Earth's mantle.
The crust is the ground that people have built the building and have grown the trees on. The mantle on the other hand is way down into the earth. It has the magma and gasses and other material in it. The difference is that we can not stand on the mantle or we will burn. the crust is the outer layer of the earth, while the mantle is inside near the core.
