I.—TECTONIC HYPOTHESES. Both external and internal geological processes are controlled by gravity and the earth's bodily movements. The circulations of matter which constitute the external processes are maintained by energy derived from the sun, whereas the internal processes derive much of their energy from the earth's internal heat, the latter being partly an inheritance, and partly an income supplied by atomic disintegration. Hypotheses relating to the physical causes of earth movements must…

Continental drift and a theory of convection
Early geologists considered that the Earth's surface is rigid and unchanging. They assumed that the whole Earth is static, except for enough sub-surface contraction to build mountains. After
A model is presented that traces quantitatively the history of geodynamic processes, from the time of origin of the Earth to the present time. Initially, the Earth underwent a slow, cool, homogeneous
The Earth expansion theory and its transition from scientific hypothesis to pseudoscientific belief
Abstract. During the first half of 20th century, the dominant global tectonics model based on Earth contraction had increasing problems accommodating new geological evidence, with the result that

Abstract Only ten years after the discovery of radium in 1897, Arthur Holmes (1890–1965) began his studies at the Royal College of Science in London where he completed the very first U/Pb age
On the building and classification of mountains
Physicists believe that known laws should suffice to explain the Earth's behavior, but the complexities of geology have defied simple explanation. Today three developments are helping to solve the
History of a discussion: selected aspects of the Earth expansion v. plate tectonics theories
Abstract A global tensional system of mid-ocean ridges was discovered at the end of the 1950s. All the world's oceans were proved to be young Mesozoic–Cenozoic structures and these new ideas in
The Current Energetics of Earth's Interior: A Gravitational Energy Perspective
The Earth's mantle convects to lose heat (Holmes, 1931); doing so drives plate tectonics (Turcotte and Oxburgh, 1967). Significant gravitational energy is created by the cooling of oceanic


The Surface-History of the Earth
A BOOK which has for its chief object the exposition of a group of geological hypotheses of a highly speculative character is likely soon to become out-of-date as geophysical evidence accumulates and
Some Problems of Physical Geology and the Earth's Thermal History
In a recent paper I stated that the hypothesis of a continuously cooling earth had “consistently failed to lead to any adequate explanations of fissure eruptions and other volcanic and tension
The Origin of Continents and Oceans
THE wide appeal of Prof. Wegener's theory of the arrangement of ocean and continent is shown by, the issue of a third greatly revised edition and of this excellent English translation. His theory is
Radioactivity and the Floor of the Oceans
Recently a mechanism allowing the escape of the heat generated by radioactivity in the basaltic under-crust of the earth has been proposed by Dr. Holmes, and a very similar one by Dr. Joly has gained
Contributions to the Theory of Magmatic Cycles
It is quite clear that Professor Joly's presentation of his theory of basaltic cycles is, taken alone, far too simple to match the complex details of geological history. In a former paper I attempted
Our Mobile Earth
PROF. DALY of Harvard once again has presented in book form matter of geological interest gathered from all parts of the world, and has supplied the desirable connective tissue of theory and
Radioactivity and the Heat of the Earth
IN his presidential address to the Geological Society, abridged in NATURE of Jan. 1, Dr. J. W. Evans refers (page 15) to the above topic in the following words: “although the whole of the energy
Physics of the Earth's Crust
MR. FISHER is well known to geologists as the writer of various important papers on Mountain Chains, Terrestrial Heat, and other physical phenomena of the earth. He has in this volume not merely
On the distribution of radium in the Earth's crust and on the Earth’s internal heat
Professor Rutherford has given a calculation which suggests that there may be enough radium in the earth to account for the temperature gradient observed near the surface. The question is of great
Past Climates
THERE are only three factors which can affect the climatic zones of the world: (a) the amount of solar radiation; (b) the horizontal transfer of heat from one part of the earth to another; and (c)
