CT: The outflow of heat from the Earth’s interior, the terrestrial heat flow, and the temperature field at depth are determined by deep-seated tectonic processes. The knowledge of the regional heat flow patterns is thus very important in geophysics and provides a useful tool for studying crustal and lithospheric structures and for understanding the nature of their evolution. Remarkable progress has been made in heat flow studies all over the world during the past few years. The rapidly growing interest in geothermics has been further enhanced by the possibility of using the geothermal energy as an alternative energy source.

N: 1. Geothermics is the science pertaining to the earth’s interior heat. Its main practical application is in finding natural concentrations of hot water, the source of Geothermal Energy, for use in electric power generation and direct heat applications such as space heating and industrial drying processes. Heat is produced within the crust and upper mantle of the earth primarily by decay of radioactive elements. This geothermal energy is transferred to the earth’s surface by diffusion and by convection movement of magma (molten rock) and deep-lying circulating water. Surface hydrothermal manifestations include hot springs, geysers, and Fumaroles.
2. In the fields of Geophysics and Energy Transformation, “geothermics” means the study of temperature distribution in the subsurface and the phenomena which influence this distribution. Geothermal energy is not transportable and therefore only of interest if there is a potential consumer nearby.
