Earth's Mantle Is More Than 100 Degrees F Hotter Than Scientists Thought

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."Having such a hot mantle could mean that the mantle is less viscous (flows more easily), which could explain how tectonic plates are able to move on top of th
