Is — Earthвђ™s Mantle

: Located between 410 km and 660 km, where extreme pressure causes minerals to change their crystalline structure, becoming much denser.

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 Earth’s mantle is

: When mantle rock melts due to changes in pressure or composition, it becomes magma. This magma rises to the surface, creating new landmasses and releasing gases that helped form our atmosphere. : Located between 410 km and 660 km,

: 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. Composition and Structure : When mantle rock melts
