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.

andrew-mc [135]

Chronic lymphocytic leukemia or the CLL  is among the most common type of leukemia affecting the adults. The lymphocytic leukemia starts in the lymphocytes. Lymphocytic leukemia is different from the lymphoma (which also occur in the lymphocytes) as it only occurs in the bone marrow and the blood. The person suffering from CLL is susceptible to an array of infections. Among the various infectious agents, the CLL patient is the most susceptible to the Staphylococcus aureus.

The person becomes susceptible to its attack as the immunity of his is weakened beacuse of the damage to the lymphoctic cells.

What are possible origins of Earth's surface and internal energy?
saul85 [17]

Answer:

The flow of heat from Earth's interior to the surface is estimated at 47±2 terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of Earth.
