The ductile part of the earth just below the lithosphere, including the lower mantle upon which the tectonic plates move. convection. A very slow circulation of a substance driven by differences in temperature and density within that substance. core. The outer layer of rock, forming a thin skin over earth"s surface. crustal rebound. The rise of earth"s crust after the removal of glacial ice. The temperature below which a material becomes magnetized. geophysics. The application of physical laws and principles to a study of earth. geothermal gradient. Rate of temperature increase associated with increasing depth beneath the surface of earth (normally about 25 c/km). gravity meter. An instrument that measures the gravitational attraction between. Earth and a mass within the instrument. heat flow. Gradual loss of heat (per unit of surface area) from earth"s interior out into space. isostasy. The balance or equilibrium between adjacent blocks of crust resting on a plastic mantle. isostatic adjustment.
