Abstract: The principal objective of this paper is to present a simple and self-consistent review of the basic physical processes controlling heat loss from the earth To accomplish this objective, we give a short summary of the oceanic and continental data and compare and contrast the respective mechanisms of heat loss In the oceans we concentrate on the effect of hydrothermal circulation, and on the continents we consider in some detail a model relating surface heat flow to varying depth scales for the distribution of potassium, thorium, and uranium From this comparison we conclude that the range in possible geotherms at depths below 100 to 150 km under continents and oceans overlaps and that the thermal structure beneath an old stable continent is indistinguishable from that beneath an ocean were it at equilibrium Oceans and continents are part of the same thermal system Both have an upper rigid mechanical layer where heat loss is by conduction and a lower thermal boundary layer where convection is dominant The simple conductive definition of the plate thickness is an oversimplification The observed distribution of area versus age in the ocean allows us to investigate the dominant mechanism of heat loss which is plate creation This distribution and an understanding of the heat flow through oceans and continents can be used to calculate the heat loss of the earth This heat loss is 1013 cal/s (42 × 1013W) of which more than 60% results from the creation of oceanic plate The relation between area and age of the oceans is coupled to the ridge and subducting slab forces that contribute to the driving mechanism for plate motions These forces are self-regulating and maintain the rate of plate generation required to achieve a balance between heat loss and heat generation
