Global Tectonics Summary
... Earth’s mantle loses its internal heat with a combination of heat conduction and convection. As part of this process, the upper 100-200 km layer of Earth cools and stiffens to form the lithosphere. Internal heat conducts through the lithosphere to the Earth surface.

Tectonic–climatic interaction
Tectonic–climatic interaction is the interrelationship between tectonic processes and the climate system. The tectonic processes in question include orogenesis, volcanism, and erosion, while relevant climatic processes include atmospheric circulation, orographic lift, monsoon circulation and the rain shadow effect. As the geological record of past climate changes over millions of years is sparse and poorly resolved, many questions remain unresolved regarding the nature of tectonic-climate interaction, although it is an area of active research by geologists and palaeoclimatologists.
