When the material gets closer to the core it gets hotter and more dense.
Seismic waves traveling through the Earth have indicated a decrease in material density in the mantle transition zone. Another indicator is the presence of magma chambers near the Earth's surface, suggesting a decrease in density as material rises from the mantle. Additionally, the behavior of gravity anomalies can also suggest a decrease in material density inside the Earth.
As depth within Earth's interior increases, the density also increases. This is because the pressure and temperature increase with depth, causing the materials in the Earth to become more compact and thus more dense.
The density is greater at the lower mantle due to the increase in pressure and temperature as you move towards the Earth's core. This denser material sinks while the less dense material rises, driving the process of mantle convection that helps drive plate tectonics.

As one progresses from the lithosphere towards the inner core of the Earth, the density generally increases. The inner core is the densest layer of the Earth due to the high pressure and temperature conditions, while the lithosphere, being the outermost layer, has lower density materials like rocks and soil.
The speed of the waves depends on the density of the material.
The density of Earth's layers increases as you move towards the Earth's core. This is because the core is made up of denser materials such as iron and nickel, which causes an increase in density compared to the less dense outer layers.

As depth increases in the Earth's crust, temperature generally increases due to the geothermal gradient. However, in the Earth's mantle, temperature decreases with depth due to adiabatic cooling. Density typically increases with depth due to the increasing pressure from the overlying layers.

The deeper you get into the earth, the more weight you have above you. This results in pressure that increases the density of the material below.
Scientists believe that the increased density of material deeper into the mantle is primarily due to the increase in pressure as you go deeper into the Earth's interior. The weight of the overlying rock layers compresses the material below, causing it to become more tightly packed and denser. Additionally, changes in mineral composition and temperature can also contribute to the increased density.

The inner core is the densest layer of the Earth due to the high pressure and temperature conditions, while the lithosphere, being the outermost layer, has lower density materials like rocks and soil.
As you go deeper into the Earth, density generally increases due to the increasing pressure and the gravitational pull of the overlying material. The Earth's inner layers, such as the mantle and core, are composed of heavier elements and minerals, contributing to higher densities. Additionally, the temperature also rises with depth, but the dominant factor affecting density is the pressure from the layers above.
The outer core of the Earth, which consists of liquid iron and nickel, represents a dramatic decrease in material density compared to the solid inner core. This decrease in density is due to the transition from solid to liquid material, resulting in a noticeable reduction in density within the outer core.
