rate of heat conduction per unit time and per unit area to the Earth's surface .
Units in which heat flow is measured are small in terms of everyday experience :
In order to determine the heat flow from the Earth , the thermal conductivity of the
rocks in an area of interest and the temperature gradient , or thermal gradient , in
this area must be measured . The thermal conductivity of a substance is a ...
The lack of any Earth's crust and upper mantle consist of six major significant
correlation between heat flow and gravity segments of plates that abut and
intersect on the surface . may be explained better by convection in the Earth's
