: 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.

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