=== Plate tectonics and heat distribution ===

The unequal distribution of the heat inside the Earth is what causes the movement of tectonic plates and all of  endogenous phenomena (Figure 3).All the áreas having higher heat flows are related to plate borders or Hot Spots.These higher flows are related,besides,to other parameters such as conrtical width,rocks thermic conductivity ,permeability, fluids ´ presence.etc.[[File: Distribution of surface heat flow.png|200|thumbnail|center|Figure 3:Distribution of surface heat flow [http://www.stewartsmithphotography.co.uk/shop/uncategorized/strokkur-geysir-national-park-iceland/].]]
