Yellowstone’s thermal features are evidence of a continued heat source not far from the earth's surface; recent volcanism is the furnace that provides the heat for Yellowstone’s geyser and hot spring activity. Hot springs, geysers, fumaroles, and mudpots are found in regions of young volcanic activi ...

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.
