: 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.
: The mantle acts as a thermal blanket, slowly releasing the primordial heat from Earth’s formation and the radioactive decay of elements, maintaining the planet's internal temperature balance. Earth’s mantle is
: Located between 410 km and 660 km, where extreme pressure causes minerals to change their crystalline structure, becoming much denser. : Extending from the crust to about 410
: 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 : 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.
