Why is the temperature between the earth core and surface not distributed linearly?
So I read somewhere that the inner core temperature of Earth might be as high as 7000 °C.
Depending on the composition of the different layers towards the surface, the temperature should decline ...

Where did the energy released due to gravitational binding energy of the Earth go? [closed]
The gravitational binding energy of the Earth is $2×10^{32} J $, so the same amount of energy must have been released during the Earth's history.
According to this and this, the current internal ...

Can the overuse of geothermal energy become an environmental concern? [duplicate]
At what power output would we be using so much geothermal energy that we cool the core enough to endanger the Earth's magnetic field and have to stop using it? Is this a conceivable concern for a ...

Could the Earth's core lose its heat?
Will all the drilling and digging to use the Earth's natural heat as geothermal energy affect the Earth's core, causing it to cool down?
If so, would it result in an ice age? If not, how does the ...
