WebMar 1, 2024 · The mantle is the mostly solid bulk of Earth’s interior. The mantle lies between Earth’s dense, superheated core and its thin outer layer, the crust. The mantle is about …
Earth's outer core is a fluid layer about 2,260 km (1,400 mi) thick, composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. The outer core begins approximately 2,889 km (1,795 mi) beneath Earth's surface at the core-mantle boundary and ends 5,150 km (3,200 mi) beneath Earth's surface at the inner core boundary. WebIt is the outer core, which is not under enough pressure to become solid. Because it is a fluid mix of iron and nickel, currents result when the Earth rotates. This flow of conductive fluid induces electric currents, which in turn creates a magnetic field.
WebThe parts near the core reach 4,000° F (2,204° C). The parts closest to the Earth's surface reach about 1,600° F (871° C). The mantle is solid, but the high heat causes the mantle to move slowly beneath the Earth's crust. The Crust. We call the outside part of a loaf of bread the crust.
