The three layers of the earth, in order from outside to inside, are the crust, the mantle and the core. The mantle is the thickest and most massive layer, while the core has the highest temperatures of anywhere in the planet.
The crust ranges between 37 and 50 kilometers in thickness, and makes up only one percent of the earth's total mass. It is made up of primarily aluminosilicates. The mantle is made up dense, semi-solid rock that is composed of magnesium silicates. It is about 2,900 kilometers thick. The core, which is part solid and part liquid, is mostly iron, and creates the magnetic field for the planet.Learn More
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.Full Answer >
The Earth's mantle is 2,900 kilometers (1,802 miles) thick. The mantle lies between the core and the outer crust layer and consists of four layers: lithosphere, asthenosphere, upper mantle and lower mantle.Full Answer >
The immense pressure from the other parts of the planet keep the extremely hot iron of the Earth's inner core from melting. The iron in the inner core maintains a temperature of around 9,000 to 13,000 degrees Fahrenheit.Full Answer >
The temperature of Earth's inner core is estimated to be between 9,000 to 13,000 degrees Fahrenheit, as stated by National Geographic. The planet's innermost region is primarily made up of a solid iron composition due to extreme levels of pressure.Full Answer >
