Question

Why does temperature increase with depth in the interior of the earth?

Answer 1

The core of earth is 6 times hotter than the surface of earth. So the deeper we go we get closer to the core and the magma surrounding it which are at high temperatures .

This is why digging deep increases the temperature at that depth.

Hope it helps.

Answer 2

Answer:

There are two answer:

1) At depth, some of the heat comes from the cooling of the Earth's core, but most is from decay of radioactive elements, mainly uranium, thorium and potassium, in rocks of the crust. This means that the geothermal gradient (the increase in temperature with depth) varies with the chemical composition and age of the rocks.

2) The core of earth is 6 times hotter than the surface of earth. So the deeper we go we get closer to the core and the magma surrounding it which are at high temperatures . This is why digging deep increases the temperature at that depth.
