It's made of a nickel-iron alloy.
The main elements in the inner core of the Earth are iron and nickel. These elements are primarily responsible for generating the Earth's magnetic field through the process of convection. The extreme pressure and temperature in the inner core keep these elements in a solid state despite their high temperatures.
The inner core is located below the outer core with a reasonably higher temperature. The outer core also contains elements such as liquid iron and nickel while the inner core has others. Sorry if I am not being giving a huge amount of details.
Outer and inner core are made of the same thing: iron and nickel
The Earth's inner core is primarily composed of iron and nickel. These elements are believed to be in a solid state despite the extreme temperature and pressure due to the inner core's high density and lack of mobility.
The inner core of the Earth is believed to be solid and composed mainly of iron. The 4 layers of the Earth include the crust, the mantle, and the inner and outer cores.
The main elements in the inner core of the Earth are iron and nickel. These elements are primarily responsible for generating the Earth's magnetic field through the process of convection. The extreme pressure and temperature in the inner core keep these elements in a solid state despite their high temperatures.
The inner core is predominately iron, with some nickel, and trace lighter elements, as far as we can deduce from current science.
The inner core of the Earth is primarily composed of iron and nickel. These elements are believed to make up about 85% of the inner core, with the remaining portion likely consisting of lighter elements such as oxygen, sulfur, and silicon.
The Earth's inner core primarily consists of iron and nickel. It is solid despite the extreme temperatures due to the immense pressure at that depth, which prevents the iron and nickel from melting. This solid inner core is surrounded by a liquid outer core, which also contains these elements.
inner core mainly consists of iron, nickel and some lighter elements outer core mainly consists of iron, some nickel.
The inner core is chiefly formed of an alloy of Iron and Nickel with many many other elements occurring in trace amounts
Inner core, which is also the innermost region of the Earth.
The Earth's core consists primarily of two sections: the outer core and the inner core. The outer core is composed mainly of liquid iron and nickel, along with lighter elements such as sulfur and oxygen. In contrast, the inner core is solid and primarily made up of iron and nickel, with some lighter elements potentially present. These elements contribute to the core's temperature, pressure, and dynamic processes, including the generation of the Earth's magnetic field.
The inner core - the centre of earth - is solid and about 780 miles (1,250 km) thick. The inner core may have a temperature up to about 13,000°F (7,200°C = 7,500 K), which is hotter than the surface of the Sun. The inner core (which has a radius of about 750 miles (1,228 km) is solid. The core is a dense ball of the elements iron and nickel.
The inner core of the Earth is primarily composed of solid iron and nickel. These elements are believed to be in a crystalline form due to the intense pressure at the center of the planet.
The Earth's inner core is a solid ball of iron and nickel with a radius of about 1,220 kilometers. It is extremely hot, with temperatures reaching up to 5,700 degrees Celsius. The inner core is surrounded by the outer core, which is liquid.
The temperature of Mars' inner core is estimated to be around 1,800-2,500 degrees Fahrenheit (1,000-1,400 degrees Celsius), similar to Earth's inner core. This heat is generated from the residual heat from the planet's formation and radioactive decay of elements within the core.
