What happens to the temperature and pressure as you move downward into the Earth?

Pressure increases and, on the average, this is causative of the increase in temperature and also the density.. ,

Explanation:

On the average, the gradients for temperature, pressure and density

are all positive with respect to the depth.

From surface to center:

Temperature range is about #0^oC-7200^oC#.

Pressure range is nearly 101325 Pa-350 mega Pa.

Density range is nearly 1+ g/cc (sea water) - 13.1 g/cc (solid

iron/nickel)

At the extreme central pressure, iron is back to the solid form,

despite that temperature (#7200^0C) is more than the Sun/s surface

temperature (#5500^oC#).

#1 Pa = 1 Newton/(meter)62 and atmospheric pressure at mean

sea level = 101325 Pa (Pa to honor Pascal)
