Plate Tectonics
... The plates float like rafts on the asthenosphere. This is a partly molten, flowing layer below the solid part of the earth’s mantle. When one plate moves, it affects all the others. The movement of some of these plates causes sea-floor spreading. Today the Atlantic Ocean is spreading. North America ...

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.
