10 Things to Know About Plate Tectonics
... 2. Movement occurs because of convection currents in the asthenosphere, which move the lithosphere on top. Mantle heats up as it approaches the core, so it rises to the top, where it cools and cycles back down toward the core, and so on and so forth. 3. Divergent plate boundaries – two plates moving ...

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.
