At what depth(km) would a rock experience temperature of 5500C?
kow [346]

Explanation:

A rock would experience a temperature of 5500°C is about the core which is at a depth of 220km.

But let us use the earth's geothermal gradient to solve this problem.

The geothermal gradient is the rate at which temperature is increasing with depth.

The geothermal gradient 25°C/km

        At 5500°C,

               5500°C x  \frac{1}{25}  \frac{k}{C}  =    220km

But this is not so in nature, there are other heat sources that contributes to increasing temperature with depth such as radioactive heat and frictional heat.
