xii. p. 545, of Prof. Mohr's interesting observations on the internal heat of the earth, I found that, according to the Jaw which seems to prevail between the depths of 700 and 3,390 feet, there will cease to be any increase at all in the temperature exactly at the depth of one ...
(1875, Heft 4), a very important paper on the causes of the internal heat of the earth. After indicating some of the objections which may be urged against the Plutonistic theory of the origin of the earth's internal heat, he discusses the data obtained by the thermometric investigation of...
Internal Sources of Energy Three Sources of the Earth’s Internal Energy (Heat) 1.Impacts of asteroids 2.Decay of radioactive elements 3.Gravitational contraction Origin of the Solar System Rotating cloud of dust and gas gathers due to gravitational forces. Rotating mass contracts and flattens wit...

The War of the Worldsby H.G. Wells The Martians come to Earth in huge cylinders, with three-legged fighting machines, chemical weapons emitting a poisonous black smoke, and heat rays that incinerate people. Humanity’s attempts to fight back seem doomed after the destruction of their powerful...
reminds me of a point to which I have intended for some time to direct attention. Prof. Rutherford (``Radio-activity,'' second edition, p. 494) has calculated that the radio-activity required to compensate for the earth's internal heat is much exceeded by the (apparent) activity of ordin...
It may not be obvious while lying in the sun on a hot summer's day, but a considerable amount of heat is also coming from below you – emanating from deep within the Earth. This heat is equivalent to more than three times the total power consumption of t

which only work is involved, theworkis equal to the change in internal energy. The law also implies that if bothheatand work are involved in the change of state of a system, then the change in internal energy is equal to the heat supplied to the system minus the work done by the ...
To investigate the pressure distribution and the structural failure under the internal explosion, the scaled tests of the earth-covered magazine were conducted under a 0.5 kg TNT explosive charge. The overpressure in the 0°, 90°, and 180° directions outside the structure and the debris ...
