Geothermal Activity
Transfer of heat
Surface manifestation
Volcanic caldera
Volcanic activity reaffirms the dynamic nature of the inner, rocky planets of the solar system. Planetary evolution proceeds dependent on terrestrial composition, mass, and distance from the Sun. The Earth is massive enough to be configured by its own gravity, but not massive enough to cause thermonuclear fusion.
“Remind me that the most fertile lands were built by the fires of volcanoes.” – Andrea Gibson
