Earthвђ™s Mantle Is Today

: Stretching from 660 km down to the core-mantle boundary, this region is under such immense pressure that the rock remains solid despite temperatures exceeding 3,000°C. Why It Matters

The mantle is essential for life on Earth for several reasons: Earth’s mantle is

Earth's mantle is the massive layer of silicate rock located between the planet's thin outer crust and its dense, super-heated core. Accounting for about , it is the engine room of our planet, driving the geological processes that shape the surface we live on. Composition and Structure : Stretching from 660 km down to the

: Heat from the core creates convection currents in the mantle. These currents act like a conveyor belt, moving tectonic plates, creating mountains, and causing earthquakes. Composition and Structure : Heat from the core

: Extending from the crust to about 410 km deep, it includes the lithosphere (the rigid top layer) and the asthenosphere , a semi-fluid zone that allows tectonic plates to slide.
