WebMay 22, 2024 · May 22, 2024 In grade-school science textbooks, Earth's mantle is usually shown in a yellow-to-orange gradient, a nebulously defined layer between the crust and the core. To geologists, the mantle is much more than that. It's a region somewhere between the cold crust and the bright heat of the core.
