Description of the earth's crust

WebEarth'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. WebJul 27, 2024 · During Earth's birth, the mantle began as an ocean of liquid magma atop the iron core. As it solidified, elements that didn't fit into the major minerals collected as a scum on top—the crust. After that, the mantle began the slow circulation it has had for the last four billion years.
