... form. A rise in temperature can cause minerals in a rock to melt, forming magma. When pressure in a rock that is hot is released, the minerals in that rock can melt, forming magma. When fluids such as water combine with rock, the composition of the rock changes. This change in composition lowers the ...

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.
