The deepest humans have dug is a meager 12 kilometers (7.5 miles). Earth has multiple layers: the crust, the mantle, the liquid outer core and the solid inner core. Astronomy Our Solar System The Earth. There needs to be a 2,700-degree F (1,500 C) difference between the inner core and the mantle to spur "thermal movements" that — along with Earth's spin — create the magnetic field. Why not? Earth’s core is the very hot, very dense center of our planet.The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle.The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles). What Is the Suez Canal and Why Is it Important? At the sun's core is gravitational attraction which results in immense temperature and pressure. NY 10036. There is also a lot of evidence regarding how the outer core of the Earth convects and that helps to establish the temperature. 7 strange things that fell from the sky. The Earth's core is a dense ball of iron and nickel. Okay, so you know how hot the center of the Earth is. That's as hot as the surface of the sun. Well, the core is about 2,900 kilometers (1,802 miles) below Earth’s surface. How old is Earth’s inner core?

He enjoys spending time with his family, traveling, and bemoaning the fact the Sonics left Seattle. So basically, the Earth has all this heat, and no good method of cooling. To recreate the conditions of the Earth's core, scientists developed a hydrogen gas gun. This is said to go down 2,900 kilometers; it's temperature is about 870 degrees Celsius. The Earth can be divided into three large sections: the mantle, inner core, and outer core. Why Do Americans Call It Soccer Instead of Football? The previously measured core temperature didn't demonstrate enough of a differential, puzzling researchers for two decades. The outer core contains a mixture of iron and nickel. But the sun's surface isn't all that hot, at least compared with its atmosphere. The core itself is about the size of a dwarf planet, like Pluto. As dense iron-rich material descends to the core, heat is released. The solid inner core is too hot to hold a permanent magnetic field (see Curie temperature) but probably acts to stabilize the magnetic field generated by the liquid outer core. These experiments pegged the melting point of iron at 4,800 C (about 8,700 F) at a pressure of 2.2 million times that is found on Earth's surface at sea level. Why aren't peanuts, pecans and almonds real nuts? Extrapolating from that measurement, scientists estimated the boundary between Earth's inner and outer core is a searing 10,832 F, give or take about 930 degrees, at a pressure of 3.3 million atmospheres (or 3.3 million times the atmospheric pressure at sea level). Thus, we have no direct evidence about the composition of the inner core. The last known source of heat is the radioactive decay of elements in the inner part of the Earth. A team of scientists has measured the melting point of iron at high precision in a laboratory, and then drew from that result to calculate the temperature at the boundary of Earth's inner and outer core — now estimated at  6,000 C (about 10,800 F).
