PLANET EARTH IS A DYNAMIC SYSTEM THAT EVOLVED

- AS PART OF THE SOLAR SYSTEM - FOR 4.6 BILLION YEARS AND CONTINUES TO

ITS STRUCTURE AND COMPOSITION REFLECT THAT ONGOING EVOLUTION

THE EVOLUTION DEPENDS ON HOW HEAT - "THE GEOLOGICAL LIFEBLOOD OF PLANETS" - IS TRANSFERRED OUT OF THE COOLING EARTH BY THERMAL CONVECTION (Hot stuff rises)

THERMAL CONVECTION CAUSES PLATE TECTONICS: PLATES OF THE EARTH'S SURFACE MOVE RELATIVE TO EACH OTHER AT A FEW mm/yr (about the speed fingernails grow)

PLATE MOTIONS CAUSE EARTHQUAKES, VOLCANOS, MOUNTAIN BUILDING AT PLATE BOUNDARIES

PLATE TECTONICS MAKES EARTH WHAT IT IS - DIFFERENT FROM NEIGHBOR PLANETS

(Mars, Venus: 3 bears principle)

PLATE MOTIONS ARE CRUCIAL FOR THE ORIGIN OF LIFE, ITS SURVIVAL, AND OUR CLIMATE

PLATE MOTIONS PROVIDE RESOURCES AS WELL AS HAZARDS TO SOCIETY

"CIVILIZATION EXISTS BY GEOLOGICAL CONSENT"
