Extremely hot rock being pressured by the crust, which is so hot it's partially melted, kind of like a half-eaten ice cream cone outside on the hottest day of summer. The mantle has much higher iron and magnesium than the crust, and it is also on the verge of melting, as it's temperature is on the very edge of the melting point. Olvine, Garnet, Spinel, and Pyroxene are minerals you would find if you could mine there, although a person would be incinerated in seconds if they managed to dig that deep. Deeper in the mantle, minerals become unstable and are replaced with mineral polymorphs, which have extremely similar chemical composition, but they do have different structures. If you need more information, one of the related searches may help you.

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.
No, we have not drilled into the upper mantle. The deepest hole ever drilled, the Kola Superdeep Borehole in Russia, reached a depth of about 7.5 miles (12 kilometers) into the Earth's crust, but it did not penetrate the mantle. The upper mantle lies beneath the Earth's crust, and drilling through it would pose significant technical and logistical challenges.
The graph that best shows the inferred density of Earth from the upper mantle to the lower mantle typically demonstrates a gradual increase in density with depth. This trend reflects the increasing pressure and temperature conditions as you move deeper into the Earth, leading to denser materials forming in the lower mantle. A line graph or a bar graph that illustrates this increase clearly, with depth on the x-axis and density on the y-axis, would effectively represent this relationship.
you will find it in earths mantle because it is a kind of an igneous rock

If it were molten, it would be called magma.
convection currents in the mantle
The lithosphere is composed of crust and hard upper mantle. The oceanic lithosphere would be hard upper mantle and basaltic oceanic crust.

Your answer would be melted rock, iron, and nickel

They will stop.
They'd stop moving.
I would call this convection currents in the mantle.
