Because towards the center of the earth, there is more mass on top of it, so there is more pressure. All of the other layers, and the stuff on top of the earth is pushing down on it from all sides. For the mantle, its only the stuff on the top of the earth that is putting pressure on it.
Diamonds are believed to be formed about 90 miles below the surface of the Earth, in the mantle. So, the weight of the Earth above them creates the pressure to form diamonds.
The degree of temperature and exertion of pressure by the molten materials (magma) within the mantle is directly proportional to its depth. This means that, the deeper you go down the mantle the higher the degree of temperature and pressure exerted.
To determine the best inferred density of Earth from the upper mantle to the lower mantle, one would typically look for a graph that displays density values increasing with depth. This trend is due to the increasing pressure and temperature conditions as you move deeper into the Earth. A graph that shows a smooth, continuous increase in density, consistent with geophysical models, would be most indicative of the mantle's density profile. Look for key markers indicating the transition zones between the upper and lower mantle, where density changes more significantly.
thez nuts
it will steady as liquid form and hot
Under gentle continuous pressure, the mantle would slowly deform and flow over long periods of time. This gradual movement of the mantle is known as mantle convection, where warmer, less dense rock rises and cooler, denser rock sinks, driving the slow movements of tectonic plates on Earth's surface.

something about pressure i guess lol :)

An example of convection in the Earth system is the movement of mantle material in the Earth's interior through the process of mantle convection. This movement of hot rock material creates the slow, continuous flow of mantle material that drives tectonic plate movements on the Earth's surface.
The degree of temperature and exertion of pressure by the molten materials (magma) within the mantle is directly proportional to its depth. This means that, the deeper you go down the mantle the higher the degree of temperature and pressure exerted.
The earth's mantle would have formed initially in the same way as the crust, by the cooling of the earth but as for the metamorphic rock that defines the earth's mantle, that would have taken millions of years of extreme heat and pressure for it to form.

The arrows in the mantle represent the movement of material within the Earth's mantle due to convection currents. These currents are driven by heat from the Earth's core, causing material to rise, cool, and sink in a continuous cycle that helps drive plate tectonics.
The melting temperature of materials is dependent on the pressure that is applied, whereby the higher the pressure, the higher the melting temperature. As such the rocks in the mantle are experiencing such a high pressure, that their melting point is driven up beyond the temperature within the Earth's mantle so they remain solid.
The Earth's mantle is not entirely liquid because the temperature and pressure conditions vary throughout the mantle. While the high temperatures in the lower mantle can cause some rock to partially melt and flow, the majority of the mantle remains solid due to the higher pressure that prevents complete melting.
