Forged in fire: The 900°C heat that built Earth’s stable continents New research reveals that Earth’s continents owe their stability to searing heat deep in the planet’s crust. At more than 900°C, radioactive elements shifted upward, cooling and strengthening the landmasses that support life. This ancient heat engine also distributed valuable minerals, giving scientists new clues for exploration and for spotting potentially habitable planets.
