The optimal dipole coordinates so ...
The plate tectonics theory explains the movement of the Earth's crust. What are the major types of plate boundaries? A. Divergent, convergent and transform B. Hot, cold and medium C. Solid, liquid and gas D. Mountainous, flat and hilly ...
Update September 17, 2024: The headline from the earth.com website readsStudy: Big Bang theory of the universe is refuted by Webb telescope observations.The discoveries of the James Web Space Telescope (JWST) have all but ended the Big Bang model and standard cosmology that goes with it. ...
In order to investigate the stochastic properties of the Earth’s internal inhomogeneities, short-wavelength random inhomogeneities are commonly characterized using stochastic medium models introducing characteristic correlation distances and mean square fractional fluctuations (e.g., Sato et al.2012). At fr...
The precondition for any theory to correctly explain the formation of earth-moon system is that such a theory or model must be built on a solid basis of the correct mechanism of planet formation. In this sense, GIH model is based on a circumstellar origin theory in which the solar system...
physical chemi颅 stry of surfaces, a new theory of the origin of the Earth's continental crust is proposed. According to this theory, the for颅 mation of the sialic crust of the Earth involved a creaming process ensuing from the spontaneous emulsification of the ''truly primitive" basic ...
The atomic ratio of 危 ( Mg + Fe + Ca + Na + K + Mn + 1 2 Al) to silicon plus 1 2 Al was calculated as a function of the depth within the earth by assuming that the mantle and crust resulted from the fractional crystallization of initial chondrite-like oxide melt and by ...

Scattering is an important effect caused by interaction of seismic wavefields with inhomogeneities of hydrocarbon reservoirs, Earth's crust and mantle. In order to study the contribution of scattering to apparent attenuation we consider plane-wave propagation in acoustic 2-D and 3-D inhomogeneous ...
The work reported here on Rayleigh Waves in a Maxwell Body is a segment of comprehensive investigation on relaxation phenomena and inelastic processes in the earth. The results of the theory presented on Rayleigh Waves in a Maxwell Body are embodied in equations which show that effects pertaining ...
