Interesting Inner Core Facts: The temperature of the inner core is believed to be approximately 5400 degrees Celsius, or 5700 Kelvin. This heat is caused by three elements: residual heat from the formation of the earth, gravitational forces from the moon and the sun, and and radioactive decay of earth's inner elements.

The inner core is the fourth layer inside the Earth. It is a solid metallic ball made mainly of iron. Here, temperatures reach extraordinary levels, estimated to be between 7,200–8,500ºF (4,000–4,700ºC). Although the inner core is very hot, it is not liquid like the outer core.

25/08/2015 · Inner Core Characteristics and Facts. The inner core has the following characteristics: It is a solid spheroid; It is approximately 5200°C (9800°F). It …

04/08/2015 · The inner core is the Earth’s deepest layer, and it is a solid iron ball that is approximately 1,500 miles in diameter. Although it is extremely hot, the iron cannot melt due to the high pressure. The inner core also consists of nickel and sulfur and smaller amounts of elements other than iron.

The inner core is the very center of the Earth, and the hottest part of the planet. It is a mainly a solid ball with a radius of about 1,220 km (760 mi), according to seismological studies . [1] [2] It is believed to consist mostly of an iron – nickel alloy and to be about the same temperature as the surface of the Sun : about 5700 K (5400 °C).

The inner core is the deepest and hottest layer of our planet. It's about 4,000 miles below the surface. Think about this: the deepest hole we've ever …

The Inner Core is about 1250 km thick and is the second smallest layer of the Earth. Although it is one of the smallest, the Inner Core is also the hottest layer.

17/08/2015 · The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles). Temperature in the inner core is about 5,200° Celsius (9,392° Fahrenheit). The pressure is nearly 3.6 million atmosphere (atm).

The inner core is the fourth layer inside the Earth. It is a solid metallic ball made mainly of iron. Here, temperatures reach extraordinary levels, estimated to be between 7,200–8,500ºF (4,000–4,700ºC). Although the inner core is very hot, it is not liquid like the outer core.
