With an equatorial radius of 6,378 km (3,963 miles), Earth is the largest of the four inner, terrestrial (rocky) planets, but it is considerably smaller than the gas giants of the outersolar system. Earth has a single natural satellite, theMoon, which orbits the planet at a mean dista...

The outer layer of the Earth’s core is believed to be liquid, whereas the inner layer of the Core is believed to be a solid as hot as theSun! Due to the unique Nickel-Iron properties of the Earth’s Core, when coupled with its rotation, The Earth is surrounded by a powerful magnet...
The outer core surrounds the inner core. This layer, comprised of iron and nickel fluids, is approximately 1 400 miles (2.300 kilometers) thick. The thickest layer between the outer core and the crust is the mantle. This hot viscous molten rock combination is approximately 1,800 miles (2,...
What is increasingly clear is that the inner core is susceptible in different ways to activity in the layers of Earth that encircle it. “The mechanics are that the outer core is circulating and making a magnetic field, and so it’s kind of pulling the inner core back and fo...
Below Earth’s crust and mantle lies the core. The outer core, a roughly 1,500-mile-thick liquid layer of rock, can reach temperatures of up to 9,932 degrees Fahrenheit. The inner core, made of solid iron and nickel, is roughly two-thirds the size of the moon and has a radius of...
The outer core flows freely around the inner core.INNER CORE4.5 billion years ago, when the Earth was formed, the heavy material sunk to the middle and these formed the inner core. The inner core has a temperature that ranges from 5,000°C – 6,000°C and is the hottest part of the...
