... Plate tectonic theory states that the Earth's surface is broken into rigid lithospheric plates that slide on top of asthenospheric mantle. The boundary between these lithosphere and asthenosphere is based on rheology (typically defined by an isotherm ~1280°C- it is not a compositional boundary). ...

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.
