The distance between the Earth's crust to the Earth's core is approximately 3,958 miles. Of this distance, the crust only makes up approximately 21 miles. Between the crust and the outer core is the mantle, which spans a distance of 1,774 miles.
The Earth's core is divided into two layers: the inner core and the outer core. The temperature of the mantle preceding the core ranges from 500 to 4,000 degrees Celsius. The core is speculated to be approximately 6,000 degrees Celsius, with a variable range of 500 degrees either way. As of 2014, the deepest distance humans have drilled into the Earth is 12 kilometers at the Kola Superdeep Borehole.Learn More
Earth's core has two parts, a solid iron inner core and a molten outer core, which is composed of a nickel-iron alloy. The outer core begins about 1,800 miles under the crust.Full Answer >
While iron and nickel form the liquid outer layer of Earth's core, the solid inner core is made mostly of iron. The iron in Earth's core is what gives the planet its magnetic field.Full Answer >
The Earth's core consists primarily of hot and solid iron and nickel. It is the innermost layer of the Earth and has a temperature of up to 13,000 degrees Fahrenheit.Full Answer >
The earth's core is divided into two layers: the outer and inner core. The outer core borders the Earth's mantle and is approximately 1,430 miles in thickness. The inner core has a thickness of 750 miles, giving the core a combined thickness of 2180 miles.Full Answer >
