Near-surface geophysics is the use of geophysical methods to investigate small-scale features in the shallow (tens of meters) subsurface. It is closely related to applied geophysics or exploration geophysics. Methods used include seismic refraction and reflection, gravity, magnetic, electric, and electromagnetic methods.
Geophysics (/ ˌ dʒ iː oʊ ˈ f ɪ z ɪ k s /) is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis.
Geomathematics (also: mathematical geosciences, mathematical geology, mathematical geophysics) is the application of mathematical methods to solve problems in geosciences, including geology and geophysics, and particularly geodynamics and seismology.
Geophysics can be described as all of the following: An academic discipline – branch of knowledge that is taught and researched at the college or university level. . Disciplines are defined (in part), and recognized by the academic journals in which research is published, and the learned societies and academic departments or faculties to which their practitioners
Based on the behavior of the waves reflected off the internal layers of the Earth, several theories developed as to what would cause variances in wave speed or loss of certain frequencies. This led to scientists like Inge Lehmann discovering the presence of the Earth's core in 1936.
Rao published several scientific articles [5] and a number of books on geophysics. [6] [7] He was an elected fellow of the Indian Academy of Sciences. [3] The Government of India awarded him the third highest civilian honour of the Padma Bhushan, in 1972, for his contributions to science. [8] He died on 4 September 1992, at the age of 86. [3]
Geophysics – the physics of the Earth and its environment in space; also the study of the Earth using quantitative physical methods; Magnetism – the study of physical phenomena that are mediated by magnetic field.
