The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the ...

"Earth's surface environment and climate have a vital influence on the deep Earth," said geologist Wan Bo.

Earth's interior is gradually cooling over time. As it cools, the liquid outer core crystallizes and becomes part of the solid inner core.
