Igneous Rocks

GEOLOGISTS RECOGNIZE THREE TYPES OF ROCKS 1) Igneous – rocks that cool from a molten state. 2) Sedimentary – rocks that form from the eroded and weathered particles of pre-existing rocks, a “re-cycled rock”. 3) Metamorphic – rocks that form by the alteration of pre-existing rocks through heat and pr ...

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.
