Plate Tectonics Might Only Occur on 0.003% of Planets. That Makes Earth Very Special Indeed.
Plate tectonics, oceans, and continents might just be the secret ingredients for complex life on Earth. And if these geological…
Did Earth’s Multicellular Life Depend on Plate Tectonics?

The Pacific Ocean Will be Gone in 300 Million Years as the World's Continents Drift and Combine
A new study determined that the world's next supercontinent, "Amasia," will form between two and three hundred million years.
How did Earth go From Molten Hellscape to Habitable Planet?
Earth formed from the Sun's protoplanetary disk about 4.6 billion years ago. In the beginning, it was a molten spheroid…
Eggshell Planets Have a Thin Brittle Crust and No Mountains or Tectonics
Planets without plate tectonics are unlikely to be habitable. But currently, we've never seen the surface of an exoplanet to…
