Itâs clear that in order to have the current balance of elements that Earth has further up, the core must be 85 percent iron and 10 percent nickel. That has meant that 5 percent of it has remained up for grabs, so to speak, to anyone who can come up with a convincing enough theory.
The earth uses that to stop solar winds and most of the radiation from the sun. The Earth has a iron-nickel core that is about 2,100 miles in radius. The inner core may have a temperature up to about 7,200Â°C, which is hotter than the surface of the Sun. The inner core which has a radius of about 1,228 km, is solid. The Layers There are four main layers of the earth. The crust, the mantle, the outer core and the inner core. the mantle is made of lava that heats near the core then rises, cools and goes back down. The crust is inhabited by humans and animals.
