Are the continents moving? What are plate tectonics?
... What cause the ocean floor to move? In the middle of the ocean where the plates are moving apart, magma is pushed up from the mantle to the surface. The upward movement of magma causes tension, or a stretch or push, on the plates. This push moves the ocean floor apart and separates the plate. Thi ...

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.
