Simplified : crust is the outer solid rock, mantel is liquid rock, and core is metal (both liquid and solid).
Why is the inner core made out of solid metal instead of solid rock
No only the outer core, the inner core is solid rock
The layers of Earth that are made of solid rock are the crust and the mantle. Though the inner core is also solid, it is made of solid iron and nickel.
The solid mineral aggregates that form the Earth's crust are rock. The plastic like mantle is formed of superheated and partially molten rock. The liquid outer core and the solid inner core are substantially formed of the element iron, along with nickel and some other elements.
From what I've read it is not made from rock but solid Iron and nickel.
the earth has 5 layers: 1) the crust - thin, rock material 2) the outer mantle - dense and mostly solid rock 3) the inner mantle - dense and solid rock 4) outer core - a liquid molten core 5) inner core -a solid metal core that's hotter than the sun's surface
No, the Earth has four main layers: the crust, the mantle, the outer core, and the inner core. The crust is the outermost layer and is made up of solid rock. Beneath the crust is the mantle, which is semi-solid. The core is composed of liquid outer core and solid inner core.
The earth's core.
Mercury is made of rock with a solid inner core.
The core is solid metal surrounded by liquid metal, the mantle is liquid rock.
The Outer core is liquid rock and metal swirling round and round. The Inner core is solid metal
