As earlier formed minerals are removed from the magma by fractional crystallization, a greater proportion of the denser elements (Fe and Mg) are removed leaving a residual melt that is more enriched in silica and lighter elements. Minerals and rocks that form later will have a greater proportion of ...

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.
