How hot are Earth's scorching insides? A sweltering 2,570 degrees Fahrenheit (1,410 degrees Celsius), a new study finds. The discovery reveals that the mantle under Earth's oceans — the area just below the crust that extends down to the planet's inner liquid core — is almost 110 degrees F (60 degrees C) hotter than scientists previously thought, the researchers said. The finding will help scientists more accurately model Earth's many geodynamic processes, including plate tectonics, they said.
