W. Jason Morgan, discoverer of plate tectonics (1935-2023)

"In 1967, Jason Morgan presented a groundbreaking paper at the annual meeting of the American Geophysical Union (AGU) in Washington DC. It showed that Earth's surface consists of about a dozen rigid plates. They are created at mid-ocean ridges, destroyed in subduction zones where they converge, and move past one another along great faults, such the San Andreas Fault in California. Other papers followed, explaining that volcanoes occur where plates subduct, mountains rise where and when continents collide, and earthquakes result from jostling and shearing at plate margins."
