How does the excess GPE of a mountain cause its base to melt?
Weisskopf suggested that the Gravitational Potential Energy (GPE) of a vertical column of mountain rock of mass $m$ must be less than the latent heat of fusion $L_f$ of the rock, i.e. $$mgh<η L_fm ...

Is there a correlation between the Earth's spin, the moon, and temperature?
Based on NASA's arcticle, changes to land, ice sheet, ocean, and mantle flow affect Earth's spin.
Does the moon's elliptical orbit around Earth also affect Earth's spin? What effect does distance play?...

How has the Earth's air pressure varied over geological time scales?
It is estimated that the Earth is losing about $5 \times 10^7 kg$ per year. Most of it due to hydrogen loss. I suppose this has an impact on the pressure of the atmosphere in general.
Thus, I am ...

How long would rising hot air from a 15,000 meter (49,000 ft) hole in the earth's surface stay warm for?
The deepest hole drilled in the earth is the Kora Borehole. At 15,000 meters (49,000 ft), the temperature was projected to reach 570 degrees F (299°C), so drilling was abandoned.
My question is, if ...
