New research evidence strong early magnetic field around Earth
2020/2/20
Deep within Earth, swirling liquid iron generates our planet's protective magnetic field. This magnetic field is invisible but is vital for life on Earth's surface: It shields the planet from harmful ...
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...
